Parenthetical citations: (Grady et al., 2019; Jerrentrup et al., 2018)
Narrative citations: Grady et al. (2019) and Jerrentrup et al. (2018)
- If a journal article has a DOI, include the DOI in the reference.
- If the journal article does not have a DOI and is from an academic research database, end the reference after the page range (for an explanation of why, see the database information page). The reference in this case is the same as for a print journal article.
- Do not include database information in the reference unless the journal article comes from a database that publishes original, proprietary content, such as UpToDate (see an example on the database information page).
- If the journal article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online journal that is not part of a database), include the URL of the article at the end of the reference.
- If the journal article has an article number instead of a page range, include the article number instead of the page range (as shown in the Jerrentrup et al. example).
Parenthetical citations: (Rabinowitz, 2019; Sapolsky, 2017)
Narrative citations: Rabinowitz (2019) and Sapolsky (2017)
- If the book includes a DOI, include the DOI in the reference after the publisher name.
- Do not include the publisher location.
- If the book does not have a DOI and comes from an academic research database, end the book reference after the publisher name. Do not include database information in the reference. The reference in this case is the same as for a print book.
Parenthetical citations: (Schaefer & Shapiro, 2019; Schulman, 2019)
Narrative citations: Schaefer and Shapiro (2019) and Schulman (2019)
- If a magazine article has a DOI, include the DOI in the reference.
- If the magazine article does not have a DOI and is from an academic research database, end the reference after the page range. Do not include database information in the reference. The reference in this case is the same as for a print magazine article.
- If the magazine article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online magazine that is not part of a database), include the URL of the article at the end of the reference.
- If the magazine article does not have volume, issue, and/or page numbers (e.g., because it is from an online magazine), omit the missing elements from the reference (as in the Schulman example).
Parenthetical citation: (Carey, 2019)
Narrative citation: Carey (2019)
- If the newspaper article is from an academic research database, end the reference after the page range. Do not include database information in the reference. The reference in this case is the same as for a print newspaper article.
- If the newspaper article has a URL that will resolve for readers (e.g., it is from an online newspaper), include the URL of the article at the end of the reference.
- If the newspaper article does not have volume, issue, and/or page numbers (e.g., because it is from an online newspaper), omit the missing elements from the reference, as shown in the example.
- If the article is from a news website (e.g., CNN, HuffPost)—one that does not have an associated daily or weekly newspaper—use the format for a webpage on a website instead.
Parenthetical citation: (Aron et al., 2019)
Narrative citation: Aron et al. (2019)
- If the edited book chapter includes a DOI, include the chapter DOI in the reference after the publisher name.
- If the edited book chapter does not have a DOI and comes from an academic research database, end the edited book chapter reference after the publisher name. Do not include database information in the reference. The reference in this case is the same as for a print edited book chapter.
- Do not create references for chapters of authored books. Instead, write a reference for the whole book and cite the chapter in the text if desired (e.g., Kumar, 2017, Chapter 2).
Parenthetical citation: (Merriam-Webster, n.d.)
Narrative citation: Merriam-Webster (n.d.)
- Because entries in Merriam-Webster’s Dictionary are updated over time and are not archived, include a retrieval date in the reference.
- Merriam-Webster is both the author and the publisher, so the name appears in the author element only to avoid repetition.
- To quote a dictionary definition, view the pages on quotations and how to quote works without page numbers for guidance. Additionally, here is an example: Culture refers to the “customary beliefs, social forms, and material traits of a racial, religious, or social group” (Merriam-Webster, n.d., Definition 1a).
Parenthetical citation: (National Cancer Institute, 2019)
Narrative citation: National Cancer Institute (2019)
The specific agency responsible for the report appears as the author. The names of parent agencies not present in the group author name appear in the source element as the publisher. This creates concise in-text citations and complete reference list entries.
Parenthetical citation: (Harvard University, 2019)
Narrative citation: Harvard University (2019)
- Use the name of the account that uploaded the video as the author.
- If the account did not actually create the work, explain this in the text if it is important for readers to know. However, if that would mean citing a source that appears unauthoritative, you might also look for the author’s YouTube channel, official website, or other social media to see whether the same video is available elsewhere.
Parenthetical citations: (APA Databases, 2019; Gates, 2019)
Narrative citations: APA Databases (2019) and Gates (2019)
- Present the name of the individual or group author the same as you would for any other reference. Then provide the Twitter handle (beginning with the @ sign) in square brackets, followed by a period.
- Provide the first 20 words of the tweet as the title. Count a URL, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
- If the tweet includes an image, a video, a poll, or a thumbnail image with a link, indicate that in brackets after the title: [Image attached], [Video attached], [Thumbnail with link attached].
- The same format used for Twitter is also used for Instagram.
Parenthetical citation: (News From Science, 2019)
Narrative citation: News From Science (2019)
- Provide the first 20 words of the Facebook post as the title. Count a URL or other link, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
- If a status update includes images, videos, thumbnail links to outside sources, or content from another Facebook post (such as when sharing a link), indicate that in square brackets.
Parenthetical citations: (Fagan, 2019; National Institute of Mental Health, 2018; Woodyatt, 2019; World Health Organization, 2018)
Narrative citations: Fagan (2019), National Institute of Mental Health (2018), Woodyatt (2019), and World Health Organization (2018)
- Provide as specific a date as is available on the webpage. This might be a year only; a year and month; or a year, month, and day.
- Italicize the title of a webpage.
- When the author of the webpage and the publisher of the website are the same, omit the publisher name to avoid repetition (as in the World Health Organization example).
- When contents of a page are meant to be updated over time but are not archived, include a retrieval date in the reference (as in the Fagan example).
- Use the webpage on a website format for articles from news websites such as CNN and HuffPost (these sites do not have associated daily or weekly newspapers). Use the newspaper article category for articles from newspaper websites such as The New York Times or The Washington Post .
- Create a reference to an open educational resources (OER) page only when the materials are available for download directly (i.e., the materials are on the page and/or can be downloaded as PDFs or other files). If you are directed to another website, create a reference to the specific webpage on that website where the materials can be retrieved. Use this format for material in any OER repository, such as OER Commons, OASIS, or MERLOT.
- Do not create a reference or in-text citation for a whole website. To mention a website in general, and not any particular information on that site, provide the name of the website in the text and include the URL in parentheses. For example, you might mention that you used a website to create a survey.
The following supplemental example references are mention in the Publication Manual:
- retracted journal or magazine article
- edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM)
- edition of the International Statistical Classification of Diseases and Related Health Problems (ICD)
- religious work
- annotated religious work
Archival document and collections are not presented in the APA Publication Manual, Seventh Edition . This content is available only on the APA Style website . This guidance has been expanded from the 6th edition.
Archival sources include letters, unpublished manuscripts, limited-circulation brochures and pamphlets, in-house institutional and corporate documents, clippings, and other documents, as well as such nontextual materials as photographs and apparatus, that are in the personal possession of an author, form part of an institutional collection, or are stored in an archive such as the Archives of the History of American Psychology at the University of Akron or the APA Archives. For any documents like these that are available on the open web or via a database (subscription or nonsubscription), follow the reference templates shown in Chapter 10 of the Publication Manual.
The general format for the reference for an archival work includes the author, date, title, and source. The reference examples shown on this page may be modified for collections requiring more or less specific information to locate materials, for different types of collections, or for additional descriptive information (e.g., a translation of a letter). Authors may choose to list correspondence from their own personal collections, but correspondence from other private collections should be listed only with the permission of the collector.
Keep in mind the following principles when creating references to archival documents and collections:
- As with any reference, the purpose is to direct readers to the source, despite the fact that only a single copy of the document may be available and readers may have some difficulty actually seeing a copy.
- Include as much information as is needed to help locate the item with reasonable ease within the repository. For items from collections with detailed finding aids, the name of the collection may be sufficient; for items from collections without finding aids, more information (e.g., call number, box number, file name or number) may be necessary to help locate the item.
- If several letters are cited from the same collection, list the collection as a reference and provide specific identifying information (author, recipient, and date) for each letter in the in-text citations (see Example 3).
- Use square brackets to indicate information that does not appear on the document.
- Use “ca.” (circa) to indicate an estimated date (see Example 5).
- Use italics for titles of archival documents and collections; if the work does not have a title, provide a description in square brackets without italics.
- Separate elements of the source (e.g., the name of a repository, library, university or archive, and the location of the university or archive) with commas. End the source with a period.
- If a publication of limited circulation is available in libraries, the reference may be formatted as usual for published material, without the archival source.
- Note that private letters (vs. those in an archive or repository) are considered personal communications and cited in the text only.
1. Letter from a repository
Frank, L. K. (1935, February 4). [Letter to Robert M. Ogden]. Rockefeller Archive Center (GEB Series 1.3, Box 371, Folder 3877), Tarrytown, NY, United States.
- Parenthetical citation: (Frank, 1935)
- Narrative citation: Frank (1935)
- Because the letter does not have a title, provide a description in square brackets.
2. Letter from a private collection
Zacharius, G. P. (1953, August 15). [Letter to William Rickel (W. Rickel, Trans.)]. Copy in possession of Hendrika Vande Kemp.
- Parenthetical citation: (Zacharius, 1953)
- Narrative citation: Zacharius (1953)
- In this example, Hendrika Vande Kemp is either the author of the paper or the author of the paper has received permission from Hendrika Vande Kemp to cite a letter in Vande Kemp’s private collection in this way. Otherwise, cite a private letter as a personal communication .
3. Collection of letters from an archive
Allport, G. W. (1930–1967). Correspondence. Gordon W. Allport Papers (HUG 4118.10), Harvard University Archives, Cambridge, MA, United States.

- Parenthetical citation: (Allport, 1930–1967, G. Boring to Allport, December 26, 1937)
- Narrative citation: Allport (1930–1967, Allport to G. Boring, March 1, 1939)
- Use the parenthetical citation format to cite a letter that E. G. Boring wrote to Allport because Allport is the author in the reference. Use either the parenthetical or narrative citation format to cite letters that Allport wrote.
4. Unpublished papers, lectures from an archive or personal collection

- Parenthetical citation: (Allport, ca. 1937)
- Narrative citation: Allport (ca. 1937)
- Because the author is reasonably certain but not stated on the document, place the word “presumed” in parentheses after the name, followed by a period.
- Because the date is reasonably certain but not stated on the document, the abbreviation “ca.” (which stands for “circa”) appears before the year in parentheses.
6. Archival source with group author

Read the full APA guidelines on citing ChatGPT
OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat
- Parenthetical citation: (OpenAI, 2023)
- Narrative citation: OpenAI (2023)
Author: The author of the model is OpenAI.
Date: The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.
Title: The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.
The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.
Bracketed text is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.
Source: When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is https://chat.openai.com/chat . For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).
What to include and what to exclude
Works included in a reference list.
The reference list provides a reliable way for readers to identify and locate the works cited in a paper. APA Style papers generally include reference lists, not bibliographies.
In general, each work cited in the text must appear in the reference list, and each work in the reference list must be cited in the text. Check your work carefully before submitting your manuscript or course assignment to ensure no works cited in the text are missing from the reference list and vice versa, with only the following exceptions.
Works Excluded From a Reference List
There are a few kinds of works that are not included in a reference list. Usually a work is not included because readers cannot recover it or because the mention is so broad that readers do not need a reference list entry to understand the use.
Information on works included in a reference list is covered in Sections 2.12 and 8.4 of the APA Publication Manual, Seventh Edition
*This guidance has been expanded from the 6th edition.*
- Personal communications such as emails, phone calls, or text messages are cited in the text only, not in the reference list, because readers cannot retrieve personal communications.
- General mentions of whole websites, whole periodicals, and common software and apps in the text do not require in-text citations or reference list entries because the use is broad and the source is familiar.
- The source of an epigraph does not usually appear in the reference list unless the work is a scholarly book or journal. For example, if you open the paper with an inspirational quotation by a famous person, the source of the quotation does not appear in the reference list because the quotation is meant to set the stage for the work, not substantiate a key point.
- Quotations from research participants in a study you conducted can be presented and discussed in the text but do not need citations or reference list entries. Citations and reference list entries are not necessary because the quotations are part of your original research. They could also compromise participants’ confidentiality, which is an ethical violation.
- References included in a meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis.
DOIs and URLs
The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.
- A DOI is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
- A URL specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.
Follow these guidelines for including DOIs and URLs in references:
- Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
- If a print work does not have a DOI, do not include any DOI or URL in the reference.
- If an online work has both a DOI and a URL, include only the DOI.
- For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
- For works without DOIs from most academic research databases , do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
- For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. See the page on including database information in references for more information.
- If the URL is no longer working or no longer provides readers access to the content you intend to cite, follow the guidance for works with no source .
- Other alphanumeric identifiers such as the International Standard Book Number (ISBN) and the International Standard Serial Number (ISSN) are not included in APA Style references.
Follow these guidelines to format DOIs and URLs:
- Present both DOIs and URLs as hyperlinks (i.e., beginning with “http:” or “https:”).
- Because a hyperlink leads readers directly to the content, it is not necessary to include the words “Retrieved from” or “Accessed from” before a DOI or URL.
- It is acceptable to use either the default display settings for hyperlinks in your word-processing program (e.g., usually blue font, underlined) or plain text that is not underlined.
- Leave links live if the work is to be published or read online.
- Follow the current recommendations of the International DOI Foundation to format DOIs in the reference list, which as of this publication is as follows:
https://doi.org/ xxxxx
- The string “https://doi.org/” is a way of presenting a DOI as a link, and “xxxxx” refers to the DOI number.
- The preferred format of the DOI has changed over time. Although older works use previous formats (e.g., “http:/dx.doi.org/” or “doi:” or “DOI:” before the DOI number), in your reference list, standardize DOIs into the current preferred format for all entries. For example, use https://doi.org/10.1037/a0040251 in your reference even though that article, published in 2016, presented the number in an older format.
- Copy and paste the DOI or URL from your web browser directly into your reference list to avoid transcription errors. Do not change the capitalization or punctuation of the DOI or URL. Do not add line breaks manually to the hyperlink; it is acceptable if your word-processing program automatically adds a break or moves the hyperlink to its own line.
- Do not add a period after the DOI or URL because this may interfere with link functionality.
When a DOI or URL is long or complex, you may use shortDOIs or shortened URLs if desired.
- Use the shortDOI service provided by the International DOI Foundation to create shortDOIs. A work can have only one DOI and only one shortDOI; the shortDOI service will either produce a new shortDOI for a work that has never had one or retrieve an existing shortDOI.
- Some websites provide their own branded shortened URLs, and independent URL shortening services are available as well. Any shortened URL is acceptable in a reference as long as you check the link to ensure that it takes you to the correct location.

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.

- Conference Paper
- Documentary
- Encyclopedia
- Google Images
- Kindle Book
- Memorial Inscription
- Museum Exhibit
- Painting or Artwork

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.

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.

APA Citation Basics. When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, like, for example, (Jones, 1998). One complete reference for each source should appear in the reference list at the end of the paper.
Parenthetical citations: (Grady et al., 2019; Jerrentrup et al., 2018) Narrative citations: Grady et al. (2019) and Jerrentrup et al.
