APA Style uses the author-date citation system (rather than footnotes or endnotes), which are often called in-text citations, parenthetical citations, or narrative citations. These are discussed in the Seventh Edition in Chapter 8, Works Credited in the Text.
To cite a source in the text of your written assignment, indicate the last name of the author(s), or if there is no author, the first few words of the document title (in quotation marks), then the page, chapter, figure, or table numbers (if applicable). Narrative citations incorporate the author's name and date of publication within the text. Parenthetical citations place the author and date in parentheses after a quotation or paraphrase. If a publication was written by an organization (such as an association, corporation, or other type of group), then you need to spell out the name of the group in full.
You must provide a specific page number (or specific part) when quoting directly from a source, and you are encouraged to to do so when paraphrasing.

1. Example of an in-text citation, personal author:
