The following supplemental example references are mention in the Publication Manual:
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Archival sources include letters, unpublished manuscripts, limited-circulation brochures and pamphlets, in-house institutional and corporate documents, clippings, and other documents, as well as such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.

Read the full APA guidelines on citing ChatGPT
OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat
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).
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.
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.*
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.
Follow these guidelines for including DOIs and URLs in references:
Follow these guidelines to format DOIs and URLs:
https://doi.org/ xxxxx
When a DOI or URL is long or complex, you may use shortDOIs or shortened URLs if desired.

Learning how to conduct accurate, discipline-specific academic research can feel daunting at first. But, with a solid understanding of the reasoning behind why we use academic citations coupled with knowledge of the basics, you’ll learn how to cite sources with accuracy and confidence.
When it comes to academic research, citing sources correctly is arguably as important as the research itself. "Your instructors are expecting your work to adhere to these professional standards," said Amanda Girard , research support manager of Shapiro Library at Southern New Hampshire University (SNHU).
With Shapiro Library for the past three years, Girard manages the library’s research support services, which includes SNHU’s 24/7 library chat and email support. She holds an undergraduate degree in professional writing and a graduate degree in library and information science. She said that accurate citations show that you have done your research on a topic and are knowledgeable about current ideas from those actively working in the field.
In other words, when you cite sources according to the academic style of your discipline, you’re giving credit where credit is due.
Citing sources properly ensures you’re following high academic and professional standards for integrity and ethics.
“When you cite a source, you can ethically use others’ research. If you are not adequately citing the information you claim in your work, it would be considered plagiarism ,” said Shannon Geary '16 , peer tutor at SNHU.
Geary has an undergraduate degree in communication from SNHU and has served on the academic support team for close to 2 years. Her job includes helping students learn how to conduct research and write academically.
“In academic writing, it is crucial to state where you are receiving your information from,” she said. “Citing your sources ensures that you are following academic integrity standards.”
According to Geary and Girard, several key reasons for citing sources are:
Ultimately, citing sources is a formalized way for you to share ideas as part of a bigger conversation among others in your field. It’s a way to build off of and reference one another’s ideas, Girard said.
Any time you use an original quote or paraphrase someone else’s ideas, you need to cite that material, according to Geary.
“The only time we do not need to cite is when presenting an original thought or general knowledge,” she said.
While the specific format for citing sources can vary based on the style used, several key elements are always included, according to Girard. Those are:
By giving credit to the authors, researchers and experts you cite, you’re building credibility. You’re showing that your argument is built on solid research.
“Proper citation not only builds a writer's authority but also ensures the reliability of the work,” Geary said. “Properly formatted citations are a roadmap for instructors and other readers to verify the information we present in our work.”
Certain disciplines adhere to specific citation standards because different disciplines prioritize certain information and research styles . The most common citation styles used in academic research, according to Geary, are:
The benefit of using the same format as other researchers within a discipline is that the framework of presenting ideas allows you to “speak the same language,” according to Girard.
Keeping track of your research as you go is one of the best ways to ensure you’re citing appropriately and correctly based on the style that your academic discipline uses.
“Through careful citation, authors ensure their audience can distinguish between borrowed material and original thoughts, safeguarding their academic reputation and following academic honesty policies,” Geary said.
Some tips that she and Girard shared to ensure you’re citing sources correctly include:
How to cite a reference in academic writing.
A citation consists of two pieces: an in-text citation that is typically short and a longer list of references or works cited (depending on the style used) at the end of the paper.
“In-text citations immediately acknowledge the use of external source information and its exact location,” Geary said. While each style uses a slightly different format for in-text citations that reference the research, you may expect to need the page number, author’s name and possibly date of publication in parentheses at the end of a sentence or passage, according to Geary.
A longer entry listing the complete details of the resource you referenced should also be included on the references or works cited page at the end of the paper. The full citation is provided with complete details of the source, such as author, title, publication date and more, Geary said.
The two-part aspect of citations is because of readability. “You can imagine how putting the full citation would break up the flow of a paper,” Girard said. “So, a shortened version is used (in the text).”
“For example, if an in-text citation reads (Jones, 2024), the reader immediately knows that the ideas presented are coming from Jones’s work, and they can explore the comprehensive citation on the final page,” she said.
The in-text citation and full citation together provide a transparent trail of the author's process of engaging with research.
“Their combined use also facilitates further research by following a standardized style (APA, MLA, Chicago), guaranteeing that other scholars can easily connect and build upon their work in the future,” Geary said.
Developing and demonstrating your research skills, enhancing your work’s credibility and engaging ethically with the intellectual contributions of others are at the core of the citation process no matter which style you use.

Generate accurate citations in MLA format automatically, with MyBib!
An MLA citation generator is a software tool designed to automatically create academic citations in the Modern Language Association (MLA) citation format. The generator will take information such as document titles, author, and URLs as in input, and output fully formatted citations that can be inserted into the Works Cited page of an MLA-compliant academic paper.
The citations on a Works Cited page show the external sources that were used to write the main body of the academic paper, either directly as references and quotes, or indirectly as ideas.
MLA style is most often used by middle school and high school students in preparation for transition to college and further education. Ironically, MLA style is not actually used all that often beyond middle and high school, with APA (American Psychological Association) style being the favored style at colleges across the country.
It is also important at this level to learn why it's critical to cite sources, not just how to cite them.
Writing citations manually is time consuming and error prone. Automating this process with a citation generator is easy, straightforward, and gives accurate results. It's also easier to keep citations organized and in the correct order.
The Works Cited page contributes to the overall grade of a paper, so it is important to produce accurately formatted citations that follow the guidelines in the official MLA Handbook .
It's super easy to create MLA style citations with our MLA Citation Generator. Scroll back up to the generator at the top of the page and select the type of source you're citing. Books, journal articles, and webpages are all examples of the types of sources our generator can cite automatically. Then either search for the source, or enter the details manually in the citation form.
The generator will produce a formatted MLA citation that can be copied and pasted directly into your document, or saved to MyBib as part of your overall Works Cited page (which can be downloaded fully later!).
MyBib supports the following for MLA style:

A citation style is a set of guidelines on how to cite sources in your academic writing . You always need a citation whenever you quote , paraphrase , or summarize a source to avoid plagiarism . How you present these citations depends on the style you follow. Scribbr’s citation generator can help!
Different styles are set by different universities, academic associations, and publishers, often published in an official handbook with in-depth instructions and examples.
There are many different citation styles, but they typically use one of three basic approaches: parenthetical citations , numerical citations, or note citations.

The clearest identifying characteristic of any citation style is how the citations in the text are presented. There are three main approaches:
Citation styles also differ in terms of how you format the reference list or bibliography entries themselves (e.g., capitalization, order of information, use of italics). And many style guides also provide guidance on more general issues like text formatting, punctuation, and numbers.
In most cases, your university, department, or instructor will tell you which citation style you need to follow in your writing. If you’re not sure, it’s best to consult your institution’s guidelines or ask someone. If you’re submitting to a journal, they will usually require a specific style.
Sometimes, the choice of citation style may be left up to you. In those cases, you can base your decision on which citation styles are commonly used in your field. Try reading other articles from your discipline to see how they cite their sources, or consult the table below.

There are many different citation styles used across different academic disciplines, but they fall into three basic approaches to citation:
Check if your university or course guidelines specify which citation style to use. If the choice is left up to you, consider which style is most commonly used in your field.

The most important thing is to choose one style and use it consistently throughout your text.

One complete reference for each source should appear in the reference list at the end of the paper.
Quotes should always be cited (and indicated with quotation marks), and you should include a page number indicating where in the source the quote can be found. Example: Quote with APA Style in-text citation. Evolution is a gradual process that "can act only by very short and slow steps" (Darwin, 1859, p. 510).
