Your literature review will contain many different sources, each needing its own individual citation. The format of those citations depends on the *type* of source (book, journal article, website, etc.).
Therefore, you need to provide the information for each source you're using in your literature review to get the correct APA citation for each. Then you'll compile all those individual citations into your reference list at the end of your paper.
For example, if you're citing a journal article, you'd use the following format (but the specifics will vary based on the article):
In-text citation: (Author's Last Name, Year, p. #) or (Author's Last Name, Year) depending on whether you directly quote or paraphrase
Reference List entry:
Author, A. A. (Year). Title of article. *Title of Journal*, *Volume*(Issue), pages. https://doi.org/xxxxxxxxx
To get help creating the individual citations, use an APA citation generator (many are available online) or consult the Publication Manual of the American Psychological Association. Remember to always double-check the generated citations for accuracy.
