Cite in APA style by including the author's last name and the year of publication, and placing them both within parentheses. For example, (Smith, 2002). Capitalize the author's last name, and place a comma between the name and the year. This citation should correspond with to the matching reference on the reference list of your paper.
Introduce the author within the sentence to use a slightly different citation specified by APA style. This consists of placing the author's last name within the sentence followed only by the year of publication. For example, "Smith (2002) states that..." When directly quoting material from another source include the author, year of publication and the page number the quote was taken from, all within parentheses. For example, (Smith, 2002, p.28). Insert "p." to indicate the page number.
Name both authors when the source being cited contains two authors. For example, (Jones & Black, 2006). Place an ampersand between the two last names. If the cited source does not have an author, use the first few words of its title.
