This page will explain how to cite sources on an APA Style References page. This list will focus on the most common kinds of sources. Use the examples below to learn how to format the citation for each kind of source. Remember that reference page citations should be double spaced, with a hanging indent, and each citation in alphabetical order by the author’s last name.
Journal Articles
Journal article citations begin with author last name, followed by first initial, then the year of publication, article title, journal title, volume and issue number, pages and DOI number if there is one.
Books/eBooks
Books are simple to cite. Citations begins with author last name and first initial, book title in italics, and lastly the name of the publisher. This format is the same for books or eBooks.

Website article with an author and a date of publication
It’s always best to find websites with the author name and date of publication if you can. Here is an example of one.
Government & Organization Websites
Government & Organization Websites will not usually list an author for their webpages. In this case, you will cite the organization itself as the author. This is known as group authorship. The idea is the group who created the article is considered the author, not any one person.
Website article with no date
Many websites will not include important information like the date of publication. The citation for these will say (n.d.) to signify no date.
Textbooks
How you cite a textbook will be vary depending on if it has an author or an editor.

Citing Dictionary or Encyclopedia Entries

Citing AI Generated Information
Only use AI for coursework if your professor has given permission. Because AI does not have an author, we will start the citation with the company that makes the AI tool followed by the year. Next, you’ll include the name of the AI tool, the version, the type of AI tool (most will be large language model), and then a link to the IA homepage. Here is an example,
OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat
