American Psychological Association (APA) style includes parenthetical in-text citations and a reference list. 

APA uses parenthetical citations as its form of in-text citation. Provide a parenthetical citation before the period directly following the information you are citing. These citations should correspond to a more detailed citation in the reference list but only need to specify a page number if directly quoting or borrowing from the source material. The essential elements for this in-text citation are the author's last name and the date for the specific publications. The last name may be omitted if the sentence states or makes clear the source material.

APA uses a reference list, an alphabetized list of sources following the end of the book or paper, for its complete list of sources referenced. This list should be titled "References" in bold and alphabetized by the first item in the citation, which, in most cases, is the author's last name. Each reference from this list must be cited in your paper and vice versa.
