How to Cite Sources

Here is a complete list for how to cite sources. Most of these guides present citation guidance and examples in MLA, APA, and Chicago.

If you’re looking for general information on MLA or APA citations , the EasyBib Writing Center was designed for you! It has articles on what’s needed in an MLA in-text citation , how to format an APA paper, what an MLA annotated bibliography is, making an MLA works cited page, and much more!

MLA Format Citation Examples

The Modern Language Association created the MLA Style, currently in its 9th edition, to provide researchers with guidelines for writing and documenting scholarly borrowings.  Most often used in the humanities, MLA style (or MLA format ) has been adopted and used by numerous other disciplines, in multiple parts of the world.

MLA provides standard rules to follow so that most research papers are formatted in a similar manner. This makes it easier for readers to comprehend the information. The MLA in-text citation guidelines, MLA works cited standards, and MLA annotated bibliography instructions provide scholars with the information they need to properly cite sources in their research papers, articles, and assignments.

APA Format Citation Examples

The American Psychological Association created the APA citation style in 1929 as a way to help psychologists, anthropologists, and even business managers establish one common way to cite sources and present content.

APA is used when citing sources for academic articles such as journals, and is intended to help readers better comprehend content, and to avoid language bias wherever possible. The APA style (or APA format ) is now in its 7th edition, and provides citation style guides for virtually any type of resource.

Chicago Style Citation Examples

The Chicago/Turabian style of citing sources is generally used when citing sources for humanities papers, and is best known for its requirement that writers place bibliographic citations at the bottom of a page (in Chicago-format footnotes ) or at the end of a paper (endnotes).

The Turabian and Chicago citation styles are almost identical, but the Turabian style is geared towards student published papers such as theses and dissertations, while the Chicago style provides guidelines for all types of publications. This is why you’ll commonly see Chicago style and Turabian style presented together. The Chicago Manual of Style is currently in its 17th edition, and Turabian’s A Manual for Writers of Research Papers, Theses, and Dissertations is in its 8th edition.

6 Interesting Citation Facts

The world of citations may seem cut and dry, but there’s more to them than just specific capitalization rules, MLA in-text citations , and other formatting specifications. Citations have been helping researches document their sources for hundreds of years, and are a great way to learn more about a particular subject area.

Ever wonder what sets all the different styles apart, or how they came to be in the first place? Read on for some interesting facts about citations!

1. There are Over 7,000 Different Citation Styles

You may be familiar with MLA and APA citation styles, but there are actually thousands of citation styles used for all different academic disciplines all across the world. Deciding which one to use can be difficult, so be sure to ask you instructor which one you should be using for your next paper.

2. Some Citation Styles are Named After People

While a majority of citation styles are named for the specific organizations that publish them (i.e. APA is published by the American Psychological Association, and MLA format is named for the Modern Language Association), some are actually named after individuals. The most well-known example of this is perhaps Turabian style, named for Kate L. Turabian, an American educator and writer. She developed this style as a condensed version of the Chicago Manual of Style in order to present a more concise set of rules to students.

3. There are Some Really Specific and Uniquely Named Citation Styles

How specific can citation styles get? The answer is very. For example, the “Flavour and Fragrance Journal” style is based on a bimonthly, peer-reviewed scientific journal published since 1985 by John Wiley & Sons. It publishes original research articles, reviews and special reports on all aspects of flavor and fragrance. Another example is “Nordic Pulp and Paper Research,” a style used by an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents.

4. More citations were created on  EasyBib.com  in the first quarter of 2018 than there are people in California.

The US Census Bureau estimates that approximately 39.5 million people live in the state of California. Meanwhile, about 43 million citations were made on EasyBib from January to March of 2018. That’s a lot of citations.

5. “Citations” is a Word With a Long History

The word “citations” can be traced back literally thousands of years to the Latin word “citare” meaning “to summon, urge, call; put in sudden motion, call forward; rouse, excite.” The word then took on its more modern meaning and relevance to writing papers in the 1600s, where it became known as the “act of citing or quoting a passage from a book, etc.”

6. Citation Styles are Always Changing

The concept of citations always stays the same. It is a means of preventing plagiarism and demonstrating where you relied on outside sources. The specific style rules, however, can and do change regularly. For example, in 2018 alone, 46 new citation styles were introduced , and 106 updates were made to exiting styles. At EasyBib, we are always on the lookout for ways to improve our styles and opportunities to add new ones to our list.

Why Citations Matter

Here are the ways accurate citations can help your students achieve academic success, and how you can answer the dreaded question, “why should I cite my sources?”

They Give Credit to the Right People

Citing their sources makes sure that the reader can differentiate the student’s original thoughts from those of other researchers. Not only does this make sure that the sources they use receive proper credit for their work, it ensures that the student receives deserved recognition for their unique contributions to the topic. Whether the student is citing in MLA format , APA format , or any other style, citations serve as a natural way to place a student’s work in the broader context of the subject area, and serve as an easy way to gauge their commitment to the project.

They Provide Hard Evidence of Ideas

Having many citations from a wide variety of sources related to their idea means that the student is working on a well-researched and respected subject. Citing sources that back up their claim creates room for fact-checking and further research . And, if they can cite a few sources that have the converse opinion or idea, and then demonstrate to the reader why they believe that that viewpoint is wrong by again citing credible sources, the student is well on their way to winning over the reader and cementing their point of view.

They Promote Originality and Prevent Plagiarism

The point of research projects is not to regurgitate information that can already be found elsewhere. We have Google for that! What the student’s project should aim to do is promote an original idea or a spin on an existing idea, and use reliable sources to promote that idea. Copying or directly referencing a source without proper citation can lead to not only a poor grade, but accusations of academic dishonesty. By citing their sources regularly and accurately, students can easily avoid the trap of plagiarism , and promote further research on their topic.

They Create Better Researchers

By researching sources to back up and promote their ideas, students are becoming better researchers without even knowing it! Each time a new source is read or researched, the student is becoming more engaged with the project and is developing a deeper understanding of the subject area. Proper citations demonstrate a breadth of the student’s reading and dedication to the project itself. By creating citations, students are compelled to make connections between their sources and discern research patterns. Each time they complete this process, they are helping themselves become better researchers and writers overall.

When is the Right Time to Start Making Citations?

Make in-text/parenthetical citations as you need them.

As you are writing your paper, be sure to include references within the text that correspond with references in a works cited or bibliography. These are usually called in-text citations or parenthetical citations in MLA and APA formats. The most effective time to complete these is directly after you have made your reference to another source. For instance, after writing the line from Charles Dickens’ A Tale of Two Cities : “It was the best of times, it was the worst of times…,” you would include a citation like this (depending on your chosen citation style):

(Dickens 11).

This signals to the reader that you have referenced an outside source. What’s great about this system is that the in-text citations serve as a natural list for all of the citations you have made in your paper, which will make completing the works cited page a whole lot easier. After you are done writing, all that will be left for you to do is scan your paper for these references, and then build a works cited page that includes a citation for each one.

2. Understand the General Formatting Rules of Your Citation Style Before You Start Writing

While reading up on paper formatting may not sound exciting, being aware of how your paper should look early on in the paper writing process is super important. Citation styles can dictate more than just the appearance of the citations themselves, but rather can impact the layout of your paper as a whole, with specific guidelines concerning margin width, title treatment, and even font size and spacing. Knowing how to organize your paper before you start writing will ensure that you do not receive a low grade for something as trivial as forgetting a hanging indent.

Don’t know where to start? Here’s a formatting guide on APA format .

3. Double-check All of Your Outside Sources for Relevance and Trustworthiness First

Collecting outside sources that support your research and specific topic is a critical step in writing an effective paper. But before you run to the library and grab the first 20 books you can lay your hands on, keep in mind that selecting a source to include in your paper should not be taken lightly. Before you proceed with using it to backup your ideas, run a quick Internet search for it and see if other scholars in your field have written about it as well. Check to see if there are book reviews about it or peer accolades. If you spot something that seems off to you, you may want to consider leaving it out of your work. Doing this before your start making citations can save you a ton of time in the long run.

Finished with your paper? It may be time to run it through a grammar and plagiarism checker , like the one offered by EasyBib Plus. If you’re just looking to brush up on the basics, our grammar guides  are ready anytime you are.

Why citing is important

It's important to cite sources you used in your research for several reasons:

• To show your reader you've done proper research by listing sources you used to get your information
• To be a responsible scholar by giving credit to other researchers and acknowledging their ideas
• To avoid plagiarism by quoting words and ideas used by other authors
• To allow your reader to track down the sources you used by citing them accurately in your paper by way of footnotes, a bibliography or reference list

About citations

Citing a source means that you show, within the body of your text, that you took words, ideas, figures, images, etc. from another place.

Citations are a short way to uniquely identify a published work (e.g. book, article, chapter, web site).  They are found in bibliographies and reference lists and are also collected in article and book databases.

Citations consist of standard elements, and contain all the information necessary to identify and track down publications, including:

• author name(s)
• titles of books, articles, and journals
• date of publication
• page numbers
• volume and issue numbers (for articles)

Citations may look different, depending on what is being cited and which style was used to create them. Choose an appropriate style guide for your needs.  Here is an example of an article citation using four different citation styles.  Notice the common elements as mentioned above:

Author - R. Langer

Article Title - New Methods of Drug Delivery

Source Title - Science

Volume and issue - Vol 249, issue 4976

Publication Date - 1990

Page numbers - 1527-1533

American Chemical Society (ACS) style:

Langer, R. New Methods of Drug Delivery. Science 1990 , 249 , 1527-1533.

IEEE Style:

R. Langer, " New Methods of Drug Delivery," Science , vol. 249 , pp. 1527-1533 , SEP 28, 1990 .

American Psychological Association   (APA) style:

Langer, R. (1990) . New methods of drug delivery. Science , 249 (4976), 1527-1533.

Modern Language Association (MLA) style:

Langer, R. " New Methods of Drug Delivery." Science 249.4976 (1990) : 1527-33.

What to cite

You must cite:

• Facts, figures, ideas, or other information that is not common knowledge

Publications that must be cited include:  books, book chapters, articles, web pages, theses, etc.

Another person's exact words should be quoted and cited to show proper credit 

When in doubt, be safe and cite your source!

Avoiding plagiarism

Plagiarism occurs when you borrow another's words (or ideas) and do not acknowledge that you have done so. In this culture, we consider our words and ideas intellectual property; like a car or any other possession, we believe our words belong to us and cannot be used without our permission.

Plagiarism is a very serious offense. If it is found that you have plagiarized -- deliberately or inadvertently -- you may face serious consequences. In some instances, plagiarism has meant that students have had to leave the institutions where they were studying.

The best way to avoid plagiarism is to cite your sources - both within the body of your paper and in a bibliography of sources you used at the end of your paper.

A citation is a formal reference to a published or unpublished source that you consulted and obtained information from while writing your research paper. It refers to a source of information that supports a factual statement, proposition, argument, or assertion or any quoted text obtained from a book, article, web site, or any other type of material . In-text citations are embedded within the body of your paper and use a shorthand notation style that refers to a complete description of the item at the end of the paper. Materials cited at the end of a paper may be listed under the heading References, Sources, Works Cited, or Bibliography. Rules on how to properly cite a source depends on the writing style manual your professor wants you to use for the class [e.g., APA, MLA, Chicago, Turabian, etc.]. Note that some disciplines have their own citation rules [e.g., law].

Reasons for Citing Your Sources

Reasons for Citing Sources in Your Research Paper

English scientist, Sir Isaac Newton, once wrote, "If I have seen further, it is by standing on the shoulders of giants.”* Citations support learning how to "see further" through processes of intellectual discovery, critical thinking, and applying a deliberate method of navigating through the scholarly landscape by tracking how cited works are propagated by scholars over time and the subsequent ways this leads to the devarication of new knowledge.

Listed below are specific reasons why citing sources is an important part of doing good research.

• Shows the reader where to find more information . Citations help readers expand their understanding and knowledge about the issues being investigated. One of the most effective strategies for locating authoritative, relevant sources about a research problem is to review materials cited in studies published by other authors. In this way, the sources you cite help the reader identify where to go to examine the topic in more depth and detail.
• Increases your credibility as an author . Citations to the words, ideas, and arguments of scholars demonstrates that you have conducted a thorough review of the literature and, therefore, you are reporting your research results or proposing recommended courses of action from an informed and critically engaged perspective. Your citations offer evidence that you effectively contemplated, evaluated, and synthesized sources of information in relation to your conceptualization of the research problem.
• Illustrates the non-linear and contested nature of knowledge creation . The sources you cite show the reader how you characterized the dynamics of prior knowledge creation relevant to the research problem and how you managed to effectively identify the contested relationships between problems and solutions proposed among scholars. Citations don't just list materials used in your study, they tell a story about how prior knowledge-making emerged from a constant state of creation, renewal, and transformation.
• Reinforces your arguments . Sources cited in your paper provide the evidence that readers need to determine that you properly addressed the “So What?” question. This refers to whether you considered the relevance and significance of the research problem, its implications applied to creating new knowledge, and its importance for improving practice. In this way, citations draw attention to and support the legitimacy and originality of your own ideas and assertions.
• Demonstrates that you "listened" to relevant conversations among scholars before joining in . Your citations tell the reader where you developed an understanding of the debates among scholars. They show how you educated yourself about ongoing conversations taking place within relevant communities of researchers before inserting your own ideas and arguments. In peer-reviewed scholarship, most of these conversations emerge within books, research reports, journal articles, and other cited works.
• Delineates alternative approaches to explaining the research problem . If you disagree with prior research assumptions or you believe that a topic has been understudied or you find that there is a gap in how scholars have understood a problem, your citations serve as the source materials from which to analyze and present an alternative viewpoint or to assert that a different course of action should be pursued. In short, the materials you cite serve as the means by which to argue persuasively against long-standing assumptions promulgated in prior studies.
• Helps the reader understand contextual aspects of your research . Cited sources help readers understand the specific circumstances, conditions, and settings of the problem being investigated and, by extension, how your arguments can be fully understood and assessed. Citations place your line of reasoning within a specific contextualized framework based on how others have studied the problem and how you interpreted their findings in support of your overall research objectives.
• Frames the development of concepts and ideas within the literature . No topic in the social and behavioral sciences rests in isolation from research that has taken place in the past. Your citations help the reader understand the growth and transformation of the theoretical assumptions, key concepts, and systematic inquiries that emerged prior to your engagement with the research problem.
• Underscores sources that were most important to you . Your citations represent a set of choices made about what you determined to be the most important sources for understanding the topic. They not only list what you discovered, but why it matters and how the materials you chose to cite fit within the broader context of your research design and arguments. As part of an overall assessment of the study’s validity and reliability , the choices you make also helps the reader determine what research may have been excluded.
• Provides evidence of interdisciplinary thinking . An important principle of good research is to extend your review of the literature beyond the predominant disciplinary space where scholars have examined a topic. Citations provide evidence that you have integrated epistemological arguments, observations, and/or the methodological strategies from other disciplines into your paper, thereby demonstrating that you understand the complex, interconnected nature of contemporary research topics.
• Supports critical thinking and independent learning . Evaluating the authenticity, reliability, validity, and originality of prior research is an act of interpretation and introspective reasoning applied to assessing whether a source of information will contribute to understanding the problem in ways that are persuasive and align with your overall research objectives. Reviewing and citing prior studies represents a deliberate act of critically scrutinizing each source as part of your overall assessment of how scholars have confronted the research problem.
• Honors the achievements of others . As Susan Blum recently noted,** citations not only identify sources used, they acknowledge the achievements of scholars within the larger network of research about the topic. Citing sources is a normative act of professionalism within academe and a way to highlight and recognize the work of scholars who likely do not obtain any tangible benefits or monetary value from their research endeavors.

Structure and Writing Style

Referencing your sources means systematically showing what information or ideas you acquired from another author’s work, and identifying where that information come from . You must cite research in order to do research, but at the same time, you must delineate what are your original thoughts and ideas and what are the thoughts and ideas of others. Citations help achieve this. Procedures used to cite sources vary among different fields of study. If not outlined in your course syllabus or writing assignment, always speak with your professor about what writing style for citing sources should be used for the class because it is important to fully understand the citation style to be used in your paper, and to apply it consistently. If your professor defers and tells you to "choose whatever you want, just be consistent," then choose the citation style you are most familiar with or that is appropriate to your major [e.g., use Chicago style if you are majoring in history; use APA if its an education course; use MLA if it is literature or a general writing course].

GENERAL GUIDELINES

1. Are there any reasons I should avoid referencing other people's work? No. If placed in the proper context, r eferencing other people's research is never an indication that your work is substandard or lacks originality. In fact, the opposite is true. If you write your paper without adequate references to previous studies, you are signaling to the reader that you are not familiar with the literature on the topic, thereby, undermining the validity of your study and your credibility as a researcher. Including references in academic writing is one of the most important ways to demonstrate your knowledge and understanding of how the research problem has been addressed. It is the intellectual packaging around which you present your thoughts and ideas to the reader.

2. What should I do if I find out that my great idea has already been studied by another researcher? It can be frustrating to come up with what you believe is a great topic only to find that it's already been thoroughly studied. However, do not become frustrated by this. You can acknowledge the prior research by writing in the text of your paper [see also Smith, 2002], then citing the complete source in your list of references. Use the discovery of prior studies as an opportunity to demonstrate the significance of the problem being investigated and, if applicable, as a means of delineating your analysis from those of others [e.g., the prior study is ten years old and doesn't take into account new variables]. Strategies for responding to prior research can include: stating how your study updates previous understandings about the topic, offering a new or different perspective, applying a different or innovative method of data gathering, and/or describing a new set of insights, guidelines, recommendations, best practices, or working solutions.

3. What should I do if I want to use an adapted version of someone else's work? You still must cite the original work. For example, you use a table of statistics from a journal article published in 1996 by author Smith, but you have altered or added new data to it. Reference the revised chart, such as, [adapted from Smith, 1996], then cite the complete original source in your list of references. You can also use other terms in order to specify the exact relationship between the original source and the version you have presented, such as, "based on data from Smith [1996]...," or "summarized from Smith [1996]...." Citing the original source helps the reader locate where the information was first presented and under what context it was used as well as to evaluate how effectively you applied it to your own research.

4. What should I do if several authors have published very similar information or ideas? You can indicate that the topic, idea, concept, or information can be found in the works of others by stating something similar to the following example: "Though many scholars have applied rational choice theory to understanding economic relations among nations [Smith, 1989; Jones, 1991; Johnson, 1994; Anderson, 2003], little attention has been given to applying the theory to examining the influence of non-governmental organizations in a globalized economy." If you only reference one author or only the most recent study, then your readers may assume that only one author has published on this topic, or more likely, they will conclude that you have not conducted a thorough review of the literature. Referencing all relevant authors of prior studies gives your readers a clear idea of the breadth of analysis you conducted in preparing to study the research problem. If there has been a significant number of prior studies on the topic [i.e., ten or more], describe the most comprehensive and recent works because they will presumably discuss and reference the older studies. However, note in your review of the literature that there has been significant scholarship devoted to the topic so the reader knows that you are aware of the numerous prior studies.

5. What if I find exactly what I want to say in the writing of another researcher? In the social sciences, the rationale in duplicating prior research is generally governed by the passage of time, changing circumstances or conditions, or the emergence of variables that necessitate new investigations . If someone else has recently conducted a thorough investigation of precisely the same research problem that you intend to study, then you likely will have to revise your topic, or at the very least, review this literature to identify something new to say about the problem. However, if it is someone else's particularly succinct expression, but it fits perfectly with what you are trying to say, then you can quote from the author directly, referencing the source. Identifying an author who has made the exact same point that you want to make can be an opportunity to add legitimacy to, as well as reinforce the significance of, the research problem you are investigating. The key is to build on that idea in new and innovative ways. If you are not sure how to do this, consult with a librarian .

6. Should I cite a source even if it was published long ago? Any source used in writing your paper should be cited, regardless of when it was written. However, in building a case for understanding prior research about your topic, it is generally true that you should focus on citing more recently published studies because they presumably have built upon the research of older studies. When referencing prior studies, use the research problem as your guide when considering what to cite. If a study from forty years ago investigated the same topic, it probably should be examined and considered in your list of references because the research may have been foundational or groundbreaking at the time, even if its findings are no longer relevant to current conditions or reflect current thinking [one way to determine if a study is foundational or groundbreaking is to examine how often it has been cited in recent studies using the "Cited by" feature of Google Scholar ]. However, if an older study only relates to the research problem tangentially or it has not been cited in recent studies, then it may be more appropriate to list it under further readings .

7. Can I cite unusual and non-scholarly sources in my research paper? The majority of the citations in a research paper should be to scholarly [a.k.a., academic; peer-reviewed] studies that rely on an objective and logical analysis of the research problem based on empirical evidence that reliably supports your arguments. However, any type of source can be considered valid if it brings relevant understanding and clarity to the topic. This can include, for example, non-textual elements such as photographs, maps, or illustrations. A source can include materials from special or archival collections, such as, personal papers, manuscripts, business memorandums, the official records of an organization, or digitized collections. Citations can also be to unusual items, such as, an audio recording, a transcript from a television news program, a unique set of data, or a social media post. The challenge is knowing how to cite unusual and non-scholarly sources because they often do not fit within standard citation rules like books or journal articles. Given this, consult with a librarian if you are unsure how to cite a source.

NOTE:   In any academic writing, you are required to identify which ideas, facts, thoughts, concepts, or declarative statements are yours and which are derived from the research of others. The only exception to this rule is information that is considered to be a commonly known fact [e.g., "George Washington was the first president of the United States"] or a statement that is self-evident [e.g., "Australia is a country in the Global South"]. Appreciate, however, that any "commonly known fact" or self-evidencing statement is culturally constructed and shaped by specific social and aesthetical biases . If you have any doubt about whether or not a fact is considered to be widely understood knowledge, provide a supporting citation, or, ask your professor for clarification about whether the statement should be cited.

Automatic Citation Generators

The links below lead to systems where you can type in your information and have a citation compiled for you. Note that these systems are not foolproof so it is important that you verify that the citation is correct and check your spelling, capitalization, etc. However, they can be useful in creating basic types of citations, particularly for online sources.

• BibMe -- APA, MLA, Chicago, and Turabian styles
• DocsCite -- for citing government publications in APA or MLA formats
• EasyBib -- APA, MLA, and Chicago styles
• Son of Citation Machine -- APA, MLA, Chicago, and Turabian styles

NOTE:   Many companies that create the research databases the USC Libraries subscribe to, such as ProQuest , include built-in citation generators that help take the guesswork out of how to properly cite a work. When available, you should always utilize these features because they not only generate a citation to the source [e.g., a journal article], but include information about where you accessed the source [e.g., the database].

What is a Citation?

A citation identifies for the reader the original source for an idea, information, or image that is referred to in a work.

• In the body of a paper, the  in-text citation  acknowledges the source of information used.
• At the end of a paper, the citations are compiled on a  References  or  Works Cited  list. A basic citation includes the author, title, and publication information of the source. 

From:  Lemieux  Library,  University  of Seattle 

Why Should You Cite?

Quoting Are you quoting two or more consecutive words from a source? Then the original source should be cited and the words or phrase placed in quotes. 

Paraphrasing If an idea or information comes from another source,  even if you put it in your own words , you still need to credit the source.  General vs. Unfamiliar Knowledge You do not need to cite material which is accepted common knowledge. If in doubt whether your information is common knowledge or not, cite it. Formats We usually think of books and articles. However, if you use material from web sites, films, music, graphs, tables, etc. you'll also need to cite these as well.

Plagiarism is presenting the words or ideas of someone else as your own without proper acknowledgment of the source. When you work on a research paper and use supporting material from works by others, it's okay to quote people and use their ideas, but you do need to correctly credit them. Even when you summarize or paraphrase information found in books, articles, or Web pages, you must acknowledge the original author.

A Quick Guide to Harvard Referencing | Citation Examples

Published on 14 February 2020 by Jack Caulfield . Revised on 15 September 2023.

Referencing is an important part of academic writing. It tells your readers what sources you’ve used and how to find them.

Harvard is the most common referencing style used in UK universities. In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list .

Harvard in-text citation, creating a harvard reference list, harvard referencing examples, referencing sources with no author or date, frequently asked questions about harvard referencing.

A Harvard in-text citation appears in brackets beside any quotation or paraphrase of a source. It gives the last name of the author(s) and the year of publication, as well as a page number or range locating the passage referenced, if applicable:

Note that ‘p.’ is used for a single page, ‘pp.’ for multiple pages (e.g. ‘pp. 1–5’).

An in-text citation usually appears immediately after the quotation or paraphrase in question. It may also appear at the end of the relevant sentence, as long as it’s clear what it refers to.

When your sentence already mentions the name of the author, it should not be repeated in the citation:

Sources with multiple authors

When you cite a source with up to three authors, cite all authors’ names. For four or more authors, list only the first name, followed by ‘ et al. ’:

Sources with no page numbers

Some sources, such as websites , often don’t have page numbers. If the source is a short text, you can simply leave out the page number. With longer sources, you can use an alternate locator such as a subheading or paragraph number if you need to specify where to find the quote:

Multiple citations at the same point

When you need multiple citations to appear at the same point in your text – for example, when you refer to several sources with one phrase – you can present them in the same set of brackets, separated by semicolons. List them in order of publication date:

Multiple sources with the same author and date

If you cite multiple sources by the same author which were published in the same year, it’s important to distinguish between them in your citations. To do this, insert an ‘a’ after the year in the first one you reference, a ‘b’ in the second, and so on:

Prevent plagiarism, run a free check.

A bibliography or reference list appears at the end of your text. It lists all your sources in alphabetical order by the author’s last name, giving complete information so that the reader can look them up if necessary.

The reference entry starts with the author’s last name followed by initial(s). Only the first word of the title is capitalised (as well as any proper nouns).

Sources with multiple authors in the reference list

As with in-text citations, up to three authors should be listed; when there are four or more, list only the first author followed by ‘ et al. ’:

Reference list entries vary according to source type, since different information is relevant for different sources. Formats and examples for the most commonly used source types are given below.

• Entire book
• Book chapter
• Translated book
• Edition of a book

Journal articles

• Print journal
• Online-only journal with DOI
• Online-only journal with no DOI
• General web page
• Online article or blog
• Social media post

Sometimes you won’t have all the information you need for a reference. This section covers what to do when a source lacks a publication date or named author.

No publication date

When a source doesn’t have a clear publication date – for example, a constantly updated reference source like Wikipedia or an obscure historical document which can’t be accurately dated – you can replace it with the words ‘no date’:

Note that when you do this with an online source, you should still include an access date, as in the example.

When a source lacks a clearly identified author, there’s often an appropriate corporate source – the organisation responsible for the source – whom you can credit as author instead, as in the Google and Wikipedia examples above.

When that’s not the case, you can just replace it with the title of the source in both the in-text citation and the reference list:

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

A Harvard in-text citation should appear in brackets every time you quote, paraphrase, or refer to information from a source.

The citation can appear immediately after the quotation or paraphrase, or at the end of the sentence. If you’re quoting, place the citation outside of the quotation marks but before any other punctuation like a comma or full stop.

In Harvard referencing, up to three author names are included in an in-text citation or reference list entry. When there are four or more authors, include only the first, followed by ‘ et al. ’

Though the terms are sometimes used interchangeably, there is a difference in meaning:

• A reference list only includes sources cited in the text – every entry corresponds to an in-text citation .
• A bibliography also includes other sources which were consulted during the research but not cited.

Using Information Legally and Ethically

Citing resources is common practice for writers engaged in any type of research. By providing citations, the writer is contributing to the ongoing scholarly discussion of the topic. Properly cited resources:

• Attribute credit where credit is due
• Provide credibility for your arguments
• Demonstrate evidence of your research
• Offer a path for your readers for ongoing scholarship
• Help avoid plagiarism

The legal and ethical issues surrounding the use of information goes beyond avoiding plagiarism and properly citing sources .

Researchers should be knowledgable about isses related to:

• freedom of speech
• intellectual property
• billions of pages of web content,
• millions of pages of proprietary content from subscription publications, and
• over 80 million student papers previously submitted to Turnitin.

Easy-to-read Originality Reports help teach students about proper citation and ensure their academic integrity.

Your instructor may choose to use the T urnitin service which is embedded within the Canvas course management system.

What are Citations?

Choosing a Citation Style

Various disciplines have preferred citation styles, depending, usually, on which bits of information about sources is most relevant to researchers. Commonly used styles are:

• APA (American Psychological Association) -  used in   psychology, education, and other social sciences (See  Basics of APA Style  tutorial.)
• MLA (Modern Language Association) -  used in literature, arts, and humanities
• Chicago -  used in the humanities and social sciences
• Turabian -   based on Chicago style, and designed for students to use with all subjects - used in many disciplines in humanities, social sciences and natural sciences
• APSA (American Political Science Association) -  used in political science ( APSA Style Manual )
• ACS (American Chemical Society)  - used in chemistry
• CSE (Council of Science Editors)  - used in biology

Your instructor may want you to use a particular style. When in doubt, ask.

The following style guide books are available on reserve at the Library Services Desk. They can be checked out for use in the Library only.

• APA ( Publication manual of the American Psychological Association , 6th ed.)
• MLA ( MLA handbook for writers of research papers , 7th ed.)
• Chicago style ( The Chicago Manual of Style , 16th ed.)
• Turabian ( A Manual for Writers of Research Papers, Theses, and Dissertations,  2013)

Citing Sources: What are citations and why should I use them?

What is a citation.

Citations are a way of giving credit when certain material in your work came from another source. It also gives your readers the information necessary to find that source again-- it provides an important roadmap to your research process. Whenever you use sources such as books, journals or websites in your research, you must give credit to the original author by citing the source. 

Why do researchers cite?

Scholarship is a conversation  and scholars use citations not only to  give credit  to original creators and thinkers, but also to  add strength and authority  to their own work.  By citing their sources, scholars are  placing their work in a specific context  to show where they “fit” within the larger conversation.  Citations are also a great way to  leave a trail  intended to help others who may want to explore the conversation or use the sources in their own work.

In short, citations

(1) give credit

(2) add strength and authority to your work

(3) place your work in a specific context

(4) leave a trail for other scholars

"Good citations should reveal your sources, not conceal them. They should honeslty reflect the research you conducted." (Lipson 4)

Lipson, Charles. "Why Cite?"  Cite Right: A Quick Guide to Citation Styles--MLA, APA, Chicago, the Sciences, Professions, and More . Chicago: U of Chicago, 2006. Print.

What does a citation look like?

Different subject disciplines call for citation information to be written in very specific order, capitalization, and punctuation. There are therefore many different style formats. Three popular citation formats are MLA Style (for humanities articles) and APA or Chicago (for social sciences articles).

MLA style (print journal article):  

Whisenant, Warren A. "How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX." Sex Roles Vol. 49.3 (2003): 179-182.

APA style (print journal article):

Whisenant, W. A. (2003) How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX. Sex Roles , 49 (3), 179-182.

Chicago style (print journal article):

Whisenant, Warren A. "How Women Have Fared as Interscholastic Athletic Administrators Since the Passage of Title IX." Sex Roles 49, no. 3 (2003): 179-182.

No matter which style you use, all citations require the same basic information:

• Author or Creator
• Container (e.g., Journal or magazine, website, edited book)
• Date of creation or publication
• Publisher 

You are most likely to have easy access to all of your citation information when you find it in the first place. Take note of this information up front, and it will be much easier to cite it effectively later.

MLA In-Text Citations: The Basics

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Guidelines for referring to the works of others in your text using MLA style are covered throughout the  MLA Handbook  and in chapter 7 of the  MLA Style Manual . Both books provide extensive examples, so it's a good idea to consult them if you want to become even more familiar with MLA guidelines or if you have a particular reference question.

Basic in-text citation rules

In MLA Style, referring to the works of others in your text is done using parenthetical citations . This method involves providing relevant source information in parentheses whenever a sentence uses a quotation or paraphrase. Usually, the simplest way to do this is to put all of the source information in parentheses at the end of the sentence (i.e., just before the period). However, as the examples below will illustrate, there are situations where it makes sense to put the parenthetical elsewhere in the sentence, or even to leave information out.

General Guidelines

• The source information required in a parenthetical citation depends (1) upon the source medium (e.g. print, web, DVD) and (2) upon the source’s entry on the Works Cited page.
• Any source information that you provide in-text must correspond to the source information on the Works Cited page. More specifically, whatever signal word or phrase you provide to your readers in the text must be the first thing that appears on the left-hand margin of the corresponding entry on the Works Cited page.

In-text citations: Author-page style

MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:

Both citations in the examples above, (263) and (Wordsworth 263), tell readers that the information in the sentence can be located on page 263 of a work by an author named Wordsworth. If readers want more information about this source, they can turn to the Works Cited page, where, under the name of Wordsworth, they would find the following information:

Wordsworth, William. Lyrical Ballads . Oxford UP, 1967.

In-text citations for print sources with known author

For print sources like books, magazines, scholarly journal articles, and newspapers, provide a signal word or phrase (usually the author’s last name) and a page number. If you provide the signal word/phrase in the sentence, you do not need to include it in the parenthetical citation.

These examples must correspond to an entry that begins with Burke, which will be the first thing that appears on the left-hand margin of an entry on the Works Cited page:

Burke, Kenneth. Language as Symbolic Action: Essays on Life, Literature, and Method . University of California Press, 1966.

In-text citations for print sources by a corporate author

When a source has a corporate author, it is acceptable to use the name of the corporation followed by the page number for the in-text citation. You should also use abbreviations (e.g., nat'l for national) where appropriate, so as to avoid interrupting the flow of reading with overly long parenthetical citations.

In-text citations for sources with non-standard labeling systems

If a source uses a labeling or numbering system other than page numbers, such as a script or poetry, precede the citation with said label. When citing a poem, for instance, the parenthetical would begin with the word “line”, and then the line number or range. For example, the examination of William Blake’s poem “The Tyger” would be cited as such:

The speaker makes an ardent call for the exploration of the connection between the violence of nature and the divinity of creation. “In what distant deeps or skies. / Burnt the fire of thine eyes," they ask in reference to the tiger as they attempt to reconcile their intimidation with their relationship to creationism (lines 5-6).

Longer labels, such as chapters (ch.) and scenes (sc.), should be abbreviated.

In-text citations for print sources with no known author

When a source has no known author, use a shortened title of the work instead of an author name, following these guidelines.

Place the title in quotation marks if it's a short work (such as an article) or italicize it if it's a longer work (e.g. plays, books, television shows, entire Web sites) and provide a page number if it is available.

Titles longer than a standard noun phrase should be shortened into a noun phrase by excluding articles. For example, To the Lighthouse would be shortened to Lighthouse .

If the title cannot be easily shortened into a noun phrase, the title should be cut after the first clause, phrase, or punctuation:

In this example, since the reader does not know the author of the article, an abbreviated title appears in the parenthetical citation, and the full title of the article appears first at the left-hand margin of its respective entry on the Works Cited page. Thus, the writer includes the title in quotation marks as the signal phrase in the parenthetical citation in order to lead the reader directly to the source on the Works Cited page. The Works Cited entry appears as follows:

"The Impact of Global Warming in North America." Global Warming: Early Signs . 1999. www.climatehotmap.org/. Accessed 23 Mar. 2009.

If the title of the work begins with a quotation mark, such as a title that refers to another work, that quote or quoted title can be used as the shortened title. The single quotation marks must be included in the parenthetical, rather than the double quotation.

Parenthetical citations and Works Cited pages, used in conjunction, allow readers to know which sources you consulted in writing your essay, so that they can either verify your interpretation of the sources or use them in their own scholarly work.

Author-page citation for classic and literary works with multiple editions

Page numbers are always required, but additional citation information can help literary scholars, who may have a different edition of a classic work, like Marx and Engels's  The Communist Manifesto . In such cases, give the page number of your edition (making sure the edition is listed in your Works Cited page, of course) followed by a semicolon, and then the appropriate abbreviations for volume (vol.), book (bk.), part (pt.), chapter (ch.), section (sec.), or paragraph (par.). For example:

Author-page citation for works in an anthology, periodical, or collection

When you cite a work that appears inside a larger source (for instance, an article in a periodical or an essay in a collection), cite the author of the  internal source (i.e., the article or essay). For example, to cite Albert Einstein's article "A Brief Outline of the Theory of Relativity," which was published in  Nature  in 1921, you might write something like this:

See also our page on documenting periodicals in the Works Cited .

Citing authors with same last names

Sometimes more information is necessary to identify the source from which a quotation is taken. For instance, if two or more authors have the same last name, provide both authors' first initials (or even the authors' full name if different authors share initials) in your citation. For example:

Citing a work by multiple authors

For a source with two authors, list the authors’ last names in the text or in the parenthetical citation:

Corresponding Works Cited entry:

Best, David, and Sharon Marcus. “Surface Reading: An Introduction.” Representations , vol. 108, no. 1, Fall 2009, pp. 1-21. JSTOR, doi:10.1525/rep.2009.108.1.1

For a source with three or more authors, list only the first author’s last name, and replace the additional names with et al.

Franck, Caroline, et al. “Agricultural Subsidies and the American Obesity Epidemic.” American Journal of Preventative Medicine , vol. 45, no. 3, Sept. 2013, pp. 327-333.

Citing multiple works by the same author

If you cite more than one work by an author, include a shortened title for the particular work from which you are quoting to distinguish it from the others. Put short titles of books in italics and short titles of articles in quotation marks.

Citing two articles by the same author :

Citing two books by the same author :

Additionally, if the author's name is not mentioned in the sentence, format your citation with the author's name followed by a comma, followed by a shortened title of the work, and, when appropriate, the page number(s):

Citing multivolume works

If you cite from different volumes of a multivolume work, always include the volume number followed by a colon. Put a space after the colon, then provide the page number(s). (If you only cite from one volume, provide only the page number in parentheses.)

Citing the Bible

In your first parenthetical citation, you want to make clear which Bible you're using (and underline or italicize the title), as each version varies in its translation, followed by book (do not italicize or underline), chapter, and verse. For example:

If future references employ the same edition of the Bible you’re using, list only the book, chapter, and verse in the parenthetical citation:

John of Patmos echoes this passage when describing his vision (Rev. 4.6-8).

Citing indirect sources

Sometimes you may have to use an indirect source. An indirect source is a source cited within another source. For such indirect quotations, use "qtd. in" to indicate the source you actually consulted. For example:

Note that, in most cases, a responsible researcher will attempt to find the original source, rather than citing an indirect source.

Citing transcripts, plays, or screenplays

Sources that take the form of a dialogue involving two or more participants have special guidelines for their quotation and citation. Each line of dialogue should begin with the speaker's name written in all capitals and indented half an inch. A period follows the name (e.g., JAMES.) . After the period, write the dialogue. Each successive line after the first should receive an additional indentation. When another person begins speaking, start a new line with that person's name indented only half an inch. Repeat this pattern each time the speaker changes. You can include stage directions in the quote if they appear in the original source.

Conclude with a parenthetical that explains where to find the excerpt in the source. Usually, the author and title of the source can be given in a signal phrase before quoting the excerpt, so the concluding parenthetical will often just contain location information like page numbers or act/scene indicators.

Here is an example from O'Neill's  The Iceman Cometh.

WILLIE. (Pleadingly) Give me a drink, Rocky. Harry said it was all right. God, I need a drink.

ROCKY. Den grab it. It's right under your nose.

WILLIE. (Avidly) Thanks. (He takes the bottle with both twitching hands and tilts it to his lips and gulps down the whiskey in big swallows.) (1.1)

Citing non-print or sources from the Internet

With more and more scholarly work published on the Internet, you may have to cite sources you found in digital environments. While many sources on the Internet should not be used for scholarly work (reference the OWL's  Evaluating Sources of Information  resource), some Web sources are perfectly acceptable for research. When creating in-text citations for electronic, film, or Internet sources, remember that your citation must reference the source on your Works Cited page.

Sometimes writers are confused with how to craft parenthetical citations for electronic sources because of the absence of page numbers. However, these sorts of entries often do not require a page number in the parenthetical citation. For electronic and Internet sources, follow the following guidelines:

• Include in the text the first item that appears in the Work Cited entry that corresponds to the citation (e.g. author name, article name, website name, film name).
• Do not provide paragraph numbers or page numbers based on your Web browser’s print preview function.
• Unless you must list the Web site name in the signal phrase in order to get the reader to the appropriate entry, do not include URLs in-text. Only provide partial URLs such as when the name of the site includes, for example, a domain name, like  CNN.com  or  Forbes.com,  as opposed to writing out http://www.cnn.com or http://www.forbes.com.

Miscellaneous non-print sources

Two types of non-print sources you may encounter are films and lectures/presentations:

In the two examples above “Herzog” (a film’s director) and “Yates” (a presentor) lead the reader to the first item in each citation’s respective entry on the Works Cited page:

Herzog, Werner, dir. Fitzcarraldo . Perf. Klaus Kinski. Filmverlag der Autoren, 1982.

Yates, Jane. "Invention in Rhetoric and Composition." Gaps Addressed: Future Work in Rhetoric and Composition, CCCC, Palmer House Hilton, 2002. Address.

Electronic sources

Electronic sources may include web pages and online news or magazine articles:

In the first example (an online magazine article), the writer has chosen not to include the author name in-text; however, two entries from the same author appear in the Works Cited. Thus, the writer includes both the author’s last name and the article title in the parenthetical citation in order to lead the reader to the appropriate entry on the Works Cited page (see below).

In the second example (a web page), a parenthetical citation is not necessary because the page does not list an author, and the title of the article, “MLA Formatting and Style Guide,” is used as a signal phrase within the sentence. If the title of the article was not named in the sentence, an abbreviated version would appear in a parenthetical citation at the end of the sentence.

Multiple citations

To cite multiple sources in the same parenthetical reference, separate the citations by a semi-colon:

Time-based media sources

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference. For example: (00:02:15-00:02:35).

When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations, or common knowledge (For example, it is expected that U.S. citizens know that George Washington was the first President.). Remember that citing sources is a rhetorical task, and, as such, can vary based on your audience. If you’re writing for an expert audience of a scholarly journal, for example, you may need to deal with expectations of what constitutes “common knowledge” that differ from common norms.

Other Sources

The MLA Handbook describes how to cite many different kinds of authors and content creators. However, you may occasionally encounter a source or author category that the handbook does not describe, making the best way to proceed can be unclear.

In these cases, it's typically acceptable to apply the general principles of MLA citation to the new kind of source in a way that's consistent and sensible. A good way to do this is to simply use the standard MLA directions for a type of source that resembles the source you want to cite.

You may also want to investigate whether a third-party organization has provided directions for how to cite this kind of source. For example, Norquest College provides guidelines for citing Indigenous Elders and Knowledge Keepers⁠ —an author category that does not appear in the MLA Handbook . In cases like this, however, it's a good idea to ask your instructor or supervisor whether using third-party citation guidelines might present problems.

Table of contents

In-text citations and full references.

• Secondary referencing
• Page numbers
• Citing multiple sources published in the same year by the same author

Full reference examples

Referencing consists of two elements:

• in-text citations, which are inserted in the body of your text and are included in the word count. An in-text citation gives the author(s) and publication date of a source you are referring to. If the publication date is not given, the phrase 'no date' is used instead of a date. If using direct quotations or you refer to a specific section in the source you also need the page number/s if available, or paragraph number for web pages.
• full references, which are given in alphabetical order in reference list at the end of your work and are not included in the word count. Full references give full bibliographical information for all the sources you have referred to in the body of your text.

To see a reference list and intext citations check out this example assignment on Cite Them Right .

Difference between reference list and bibliography

a reference list only includes sources you have referred to in the body of your text

a bibliography includes sources you have referred to in the body of your text AND sources that were part of your background reading that you did not use in your assignment

Examples of in-text citations

You need to include an in-text citation wherever you quote or paraphrase from a source. An in-text citation consists of the last name of the author(s), the year of publication, and a page number if relevant. There are a number of ways of incorporating in-text citations into your work - some examples are provided below. Alternatively you can see examples of setting out in-text citations in Cite Them Right .

Note: When referencing a chapter of an edited book, your in-text citation should give the author(s) of the chapter.

How To Cite Sources: In-depth Guide

Did you know that, on average, college students spend over 12 hours a week researching and writing essays? It's a considerable investment of time and energy, and the quality of your work can greatly impact your academic success. One of the critical aspects of crafting top-notch essays is the art of citing sources correctly. Whether you're in the world of psychology (APA), humanities (MLA), or history (Chicago), understanding and navigating the citation styles relevant to your field is a must.

In this comprehensive article, our college essay writing service will delve deep into the world of academic writing and the crucial role that proper source citation plays in your success. Explore the intricacies of citing sources in APA, MLA, and Chicago styles as we provide detailed guidance, real-world citing sources examples, and practical insights. Discover the nuances of citing multiple sources in one sentence, using citation generators, and citing primary sources. Additionally, we'll conduct a comparative analysis of these citation styles to help you choose the right one for your research papers. By the end of this journey, you'll be well-versed in the art of source citation and ready to elevate your academic writing to the next level.

When to Source Sources in Academic Writing?

In the realm of academic writing, citing sources accurately is far more than a mere formality; it's an ethical responsibility and a testament to the integrity of your work. Proper source citation serves as the foundation of scholarly discourse, ensuring transparency, credibility, and respect for intellectual property. By crediting the authors and researchers who've paved the way, you acknowledge the collective knowledge of your field.

Interestingly, a study by the International Journal of Educational Integrity found that improper citation practices are a leading cause of plagiarism, a serious offense in academia. In fact, plagiarism-detection software like Turnitin is now widely used to uphold academic integrity. This is where the convenience of citing sources generators becomes apparent, helping students and researchers ensure proper attribution while streamlining the citation process, whether they're citing sources in Chicago style or other formats.

Moreover, accurate citations, including a parenthetical citation, allow readers to trace your sources, verify your claims, and engage in meaningful discussions. They act as a bridge between your work and the wealth of research that precedes it. In essence, mastering the art of source citation is not just about compliance with formatting rules; it's about participating in a respectful and dynamic conversation within your academic community while giving due credit to the sources, particularly when citing primary sources, that have contributed to the intellectual growth of your field.

APA Citation Style Basics

American Psychological Association (APA) style is a widely used and meticulously structured citation format primarily designed for disciplines in the social sciences. Understanding the fundamentals of APA format citing sources is vital for any student or researcher in psychology, sociology, education, and related fields. Here are some key insights into the world of APA citations from our ‘ do my paper ’ experts:

• In-text Citations with Precision : In APA style, in-text citations are concise and informative. For instance, consider this sentence: 'The impact of climate change on coastal ecosystems is a growing concern (Johnson, 2018).' In this case, 'Johnson' is the author's last name, and '2018' is the publication year. This format allows readers to quickly identify and locate the source in the reference list (Johnson, 2018).
• The Role of the Reference List : The reference list in APA style is like the treasure trove of your sources. It's a comprehensive list of all the materials you've cited in your work. For example, a reference entry for a journal article would look like this: Johnson, S. (2018). Climate Change Effects on Coastal Biodiversity . Environmental Studies, 36 (3), 255-269.
• DOI and Electronic Sources : In the digital age, many sources are found online, which is why APA has introduced the Digital Object Identifier (DOI) system. For instance, an APA citation for an online journal article with a DOI might look like this: Smith, P. (2021). Renewable Energy Solutions for Sustainable Future . Environmental Science Review, 45 (2), 101-120. https://doi.org/10.12345/esr.2021.2.101
• Citing Multiple Sources in One Sentence APA : APA rules for citing multiple sources in a single sentence are clear and practical. Consider this example for citing two sources in one sentence APA: 'Several studies (Smith, 2021; Johnson, 2018) have highlighted the urgency of addressing climate change's impact on coastal ecosystems.' Here, both sources are listed chronologically, creating a seamless flow of information in your text.
• The Power of Consistency : Consistency is a cornerstone of APA style. From the formatting of headings (e.g., Level 1, Level 2) to the use of italics for titles and the ordering of elements in a reference entry, adhering to the APA guidelines ensures your work looks polished and professional.
• Evolving Rules : As research methods and publishing practices evolve, so do citation styles. It's essential to stay updated with the latest APA publication manual as they adapt to the changing landscape of academic communication (American Psychological Association, 2020).

MLA Citation Style Basics

The Modern Language Association (MLA) citation style is the hallmark of academic writing in the humanities, literature, and related fields. It's known for its simplicity, elegance, and focus on clarity. Here's a concise guide from our argumentative essay writing service to help you navigate the intricacies of MLA format citing sources:

• In-text Citations with Author-Page Format : Citing sources MLA style primarily uses a simple author-page format for in-text citations. For example, 'In his renowned work, Shakespeare explores themes of love and fate (Smith 45).' Here, 'Smith' is the author's last name, and '45' is the page number. This format allows readers to locate the corresponding entry in the Works Cited page.
• The Works Cited Page : The Works Cited page is the heart of MLA citation. It's a detailed list of all the sources you've referenced in your paper. Each entry follows a specific format, including the author's name, source title, publication information, and more.
• Citing Digital and Print Sources : MLA is adaptable to both digital and print sources. For a print book, an MLA citation would look like this: Smith, John. The Art of Writing . Random House, 2020. For an online article, you might format it as follows: Johnson, Sarah. 'The Digital Literary Landscape.' Digital Humanities Review , vol. 28, no. 3, 2021, www.example.com/dhr/28-3/johnson.
• Citing Multiple Works by the Same Author : When citing multiple works by the same author, use a shortened version of the title to differentiate them. For instance, (Smith, Art of Writing 34) and (Smith, 'Literary Exploration' 18).
• The Importance of Punctuation and Formatting : Proper punctuation and formatting are essential in MLA citation. Pay attention to italics for titles, quotation marks for short works, and the correct use of commas, periods, and colons.
• Evolving Guidelines : MLA citing sources guidelines are known for evolving with technology and research methods. Staying up-to-date with the latest MLA handbook is crucial to ensure your citations align with current standards.

Chicago Citation Style Basics

The Chicago citation style, often used in history, arts, and social sciences, is a versatile and comprehensive system known for its flexibility and depth. Here's a guide to help you embrace the intricacies of Chicago citation:

• Two Distinct Documentation Systems : Chicago offers two documentation systems: the Notes and Bibliography system (commonly used in history and the humanities) and the Author-Date system (preferred in the social sciences). Understanding which system your discipline employs is crucial.
• Footnotes and Endnotes : In the Notes and Bibliography system, footnotes or endnotes are used to cite sources within the text. For example, 'The Industrial Revolution transformed society in profound ways. [1]' The corresponding note at the bottom of the page or end of the chapter provides full citation details.
• Bibliography or Reference List : In Chicago, both systems require a comprehensive bibliography at the end of your work, which lists all the sources you've cited. Each entry should include elements like the author's name, title, publisher, and publication date.
• Citing primary sources Chicago style : Chicago is particularly celebrated for its approach to citing primary sources, such as archival documents, letters, and manuscripts. It demands specific details about the source's origin, location, and access date, ensuring a comprehensive record.
• Citing Multiple Sources in One Footnote Chicago : When citing multiple sources in one footnote, list them in chronological order, separated by semicolons. For example, 'The 19th century saw significant advancements in technology and communication.[1];[2].'
• The Emphasis on Publication Details : Chicago places a strong emphasis on providing extensive publication information for each source cited. This includes details like the place of publication and specific page numbers in the case of print sources.
• Evolving Standards : Just like other citation styles, Chicago's guidelines evolve over time to accommodate changes in research practices. Staying informed about the latest Chicago Manual of Style editions is essential for accurate citations.

APA vs. MLA vs. Chicago: Key Similarities and Differences

Citation styles play a pivotal role in academic writing, helping maintain consistency, credibility, and clarity in scholarly work. Among the most widely used styles are APA (American Psychological Association), MLA (Modern Language Association), and Chicago. Let's explore the key similarities and differences between these three major citation styles.

Similarities:

• In-text Citations : All three styles use in-text citations to acknowledge the sources of information. In-text citations allow readers to identify the corresponding entry in the reference list or bibliography.
• Reference Lists or Bibliographies : APA, MLA, and Chicago all require a list of references, works cited, or a bibliography at the end of the document. These lists provide complete details about the sources cited in the text.
• Author and Publication Year : Both APA and MLA styles include the author's last name and the publication year within in-text citations. This allows readers to easily locate the source in the reference list.
• Digital Object Identifiers (DOIs) : APA and MLA provide guidelines for citing sources with DOIs, ensuring the accuracy and stability of online references.

Differences:

Disciplines and Focus:

• APA is primarily used in the social sciences, including psychology, sociology, and education, with a focus on empirical research and concise, structured writing.
• MLA is widely employed in humanities disciplines, such as literature and language studies, emphasizing the analysis of literary and cultural texts.
• Citing sources Chicago style is versatile, used in history, arts, and social sciences, offering both Notes and Bibliography and Author-Date systems to accommodate different research needs.

In-text Citation Styles:

• APA uses an author-date format, e.g., (Smith, 2020), for in-text citations.
• MLA uses an author-page format, e.g., (Smith 45), for in-text citations.
• Chicago uses footnotes or endnotes, which provide full citations in superscript numbers within the text and often a bibliographic entry at the bottom of the page or the end of a chapter.

Reference List/Bibliography Format:

• APA organizes the reference list alphabetically by the author's last name, followed by the publication date.
• MLA arranges the works cited list alphabetically by the author's last name and, if there is no author, by the title.
• Chicago's Notes and Bibliography system uses footnotes or endnotes for citations and a bibliography, while the Author-Date system includes an alphabetically-arranged reference list.

Handling Multiple Sources in One Citation:

• APA typically lists multiple sources in one in-text citation using semicolons, e.g., (Smith, 2020; Johnson, 2019).
• MLA uses commas to separate multiple sources within one in-text citation, e.g., (Smith 45, Johnson 22).
• Chicago usually utilizes footnotes or endnotes to cite multiple sources, each source marked with a superscript number in the text.

Citing Page Numbers:

• In APA and MLA, page numbers are often included in in-text citations for direct quotations, e.g., (Smith, 2020, p. 25) or (Smith 25).
• Chicago uses footnotes or endnotes to include page numbers for direct quotations within the text itself.

Final Thoughts

In conclusion, mastering the nuances of APA, MLA, and Chicago citation styles, including the specific requirements for citing primary sources, is an invaluable skill for academic success. It will also be a helpful guide as you explore how to write a college admission essay . These styles empower you to engage in scholarly conversation while maintaining the integrity of your research. Choose the one that best aligns with your field and project, and remember that accurate citation not only upholds academic standards but also showcases your commitment to excellence in your work.

How Marketers Can Adapt to LLM-Powered Search

• Stefano Puntoni,
• Mike Ensing,
• Jarvis Bowers

With the addition of AI-generated overviews, Google, Perplexity, OpenAI and other search engines are changing how consumers find information.

Large language models (LLMs) provide a search experience that’s dramatically different from the web-browser experience. The biggest difference is this: LLMs promise to answer queries not with links, as web browsers do, but with answers . Increasingly, using apps such as ChatGPT or Perplexity, or search portals such as Google’s Search Generative Experience (now AI Overviews) or Bing’s Copilot, customers will learn about products and brands through natural-language outputs. And that process, which will be highly consultative and conversational, will create a new information pipeline that marketers need to monitor to ensure their brands are presented for relevant prompts and described accurately. The authors present three ways for marketers to rise to this challenge.

For millions of consumers around the world, Google is the access point to the internet — and as a result, the company today enjoys a 91% market share in the $50 billion market for search ads. However, thanks to the advent of large language models (LLMs), a shakeup now seems possible for the first time in two decades.

How Americans and Israelis view one another and the U.S. role in the Israel-Hamas war

The United States continues to support Israel in its war against Hamas, but relations appear increasingly strained between the two countries and their leaders . The war also seems to have affected public opinion in both countries: Americans and Israelis now see one another’s leaders more negatively than in the recent past, and other key views have shifted as well.

Below, we explore American and Israeli public opinion in detail. This analysis is based on two Pew Research Center surveys of U.S. adults – one conducted in February and one in early April – as well as a survey of Israeli adults conducted in March and early April.

Pew Research Center analyzed Americans’ and Israelis’ attitudes on a variety of questions related to the Israel-Hamas war. The recent U.S. data is from two polls: a survey of 12,693 U.S. adults conducted Feb. 13-25, 2024, and a survey of 3,600 U.S. adults conducted April 1-7, 2024. The data for Israel is from a survey of 1,001 Israeli adults conducted March 3-April 4, 2024. 

Most of the respondents in the February survey of U.S. adults (10,642) are members of the Center’s American Trends Panel (ATP). The ATP is an online survey panel that is recruited through national, random sampling of residential addresses, which gives nearly all U.S. adults a chance of selection. Read more about the ATP’s methodology .

The remaining 2,051 respondents are members of three other survey panels – Ipsos’ KnowledgePanel, SSRS’s Opinion Panel, and NORC at the University of Chicago’s AmeriSpeak Panel – who were interviewed because they identify as Jewish or Muslim.

The February survey “oversampled” (i.e., interviewed a disproportionately large number of) Jews and Muslims to provide more reliable estimates of their views. But these groups are not overrepresented in the national figures reported, because we adjusted for the oversampling in the weighting of the data.

Although the February survey included questions about where U.S. adults were born and whether they identify as Arab or of Arab origin, there was insufficient sample size to analyze Arab Americans or people of Palestinian descent separately. In that survey , only about a quarter of U.S. Muslims identified as Arab or of Arab ancestry. As a result, in our U.S. analysis, we describe differences between religious groups, rather than differences in opinion between Arab Americans and Jewish Americans. In contrast, our surveys in Israel have sufficient samples to allow comparisons between Israeli Arabs and Israeli Jews.

Both U.S. surveys are weighted to be representative of the U.S. adult population by gender, race, ethnicity, partisan affiliation, education, religious affiliation and other categories.

The survey of Israeli adults was conducted face-to-face. Interviews were conducted in Hebrew and Arabic, and the survey is representative of the adult population ages 18 and older, excluding those in East Jerusalem and non-sanctioned outposts. (The survey also does not include the West Bank or Gaza.) The survey included an oversample of Arabs in Israel. It was subsequently weighted to be representative of the Israeli adult population with the following variables: gender by ethnicity, age by ethnicity, education, region, urbanicity and probability of selection of respondent.

Here are the February and April questions and responses for the United States used for this analysis, and the questions and responses for Israel . Here are the February and April survey  methodologies for the U.S. , and the survey methodology for Israel .

Americans have less confidence in Israeli Prime Minister Benjamin Netanyahu than Israelis have in U.S. President Joe Biden. Only 30% of U.S. adults express some or a lot of confidence in Netanyahu, while around half (53%) have not too much or no confidence in him. An additional 15% say they have not heard of him.

By contrast, more than half of Israeli adults (57%) have some or a great deal of confidence in Biden to do the right thing regarding world affairs, whereas 42% have little or no confidence in him.

Americans’ views of Netanyahu have turned more negative over the past year. The share of Americans with little or no confidence in Netanyahu to do the right thing regarding world affairs is up 11 percentage points since March 2023 (42% then, 53% today).

Democrats are more likely than Republicans to have a negative view of Netanyahu. Approximately seven-in-ten Democrats and Democratic-leaning independents (71%) have little or no confidence in him, up from 56% in 2023. Around a third of Republicans and GOP leaners (34%) now take this view – up from 29% in 2023.

Israelis’ opinions of Biden have also turned more negative. While 57% of Israelis express a lot or some confidence in Biden, that’s down from 68% last year . The share of Israelis who have no confidence at all in Biden has doubled, from 9% to 18%.

Israeli Jews and Arabs differ widely in their views of the U.S. president: 66% of Jews have confidence in Biden, but only 21% of Arabs agree. Among both groups, overall confidence in Biden has decreased by 10 points since last year.

Older Israelis, as well as those in the ideological center or on the right, have more confidence in Biden than younger and left-leaning Israelis do.

The share of Israelis with a favorable opinion of the U.S. has declined. While a broad majority of Israelis (77%) continue to see the U.S. favorably, this is down 10 points since last year. This marks the lowest overall rating of the U.S. in Israeli public opinion since 2011, based on our nearly two-decade trend .

Views of the U.S. are significantly more positive among Jewish Israelis (90%) than Arab Israelis (29%). They are also much more positive among Israelis who place themselves on the ideological right (85%) or in the center (84%) than on the left (55%).

Since last year, views of the U.S. have soured among most demographic groups in Israel, but particularly among Arab Israelis and people on the ideological left.

Americans’ views of the Israeli people are broadly positive, but far fewer express favorable views of the Israeli government . In our recent U.S. polling, we have asked separately about views of the Israeli government and the Israeli people , rather than ask a single question about views of Israel. ( Past research suggests that views of the country tend to fall somewhere between views of its people and its government.)

In our survey this past February, 64% of Americans had a favorable view of the Israeli people, while 41% voiced a favorable view of the Israeli government. Both of these figures were down modestly from 2022. Views of the Israeli people have ticked downward more among younger Americans than among older ones.

Americans and Israelis alike are divided over whether Biden is favoring one side too much in the Israel-Hamas war. In our February survey, Americans were about evenly split as to whether Biden was favoring the Israelis too much (22%), favoring the Palestinians too much (16%) or striking the right balance (21%). However, the largest share of all – 40% – was not sure.

In Israel, 41% of adults say Biden is striking the right balance, but nearly equal shares say the U.S. president favors the Israelis too much (27%) or favors Palestinians too much (25%). Just 7% of Israelis aren’t sure or did not answer the question. (It’s important to note that U.S. respondents took the survey online and were given an explicit “Don’t know” option. Israeli respondents, interviewed in person, were not. Previous research shows that offering an explicit “Don’t know” option in online surveys is a better comparison with face-to-face survey data.)

In both the U.S. and Israel , people on the ideological left are more likely than those on the right to say Biden is favoring Israelis too much (in the U.S., ideology was measured as liberal, moderate and conservative).

In the U.S., Muslim Americans are far more likely than Jewish Americans to say Biden favors the Israelis too much (60% vs. 13%). In Israel, Arabs (86%) are much more likely than Jews to say the same (86% vs. 11%). (In the U.S., we “oversampled” Muslim and Jewish Americans but did not have sufficient sample size to analyze Arab Americans. For more details on the sampling, read the “How we did this” box.)

Around seven-in-ten Israelis (72%) want to see the U.S. play a major diplomatic role in resolving the Israel-Hamas war, but Americans are more divided. In the U.S., a majority of Americans (55%) also say the U.S. should play a role in ending the war, but more favor a minor role than a major one (35% vs. 20%). Another 27% want the U.S. to play no role at all – a view shared by only 10% of Israelis.

Americans on the ideological left are more supportive of the U.S. playing a major role than are those in the center or on the right. In Israel, U.S. involvement is broadly popular across the ideological spectrum.

In the U.S., 45% of Jews think the U.S. should play a major role in resolving the war, compared with 27% of Muslims. In Israel, Jews and Arabs are both generally supportive of the U.S. playing a major role (74% and 62%, respectively).
