Cite a single author of a book by placing the author's last name followed by the page number in parentheses after an excerpt from the book that does not mention the author's name. For example, "(Lacey 45)." If you do mention the author's name in the sentence, place only the corresponding page number in parentheses. For example, "(45)." In both cases, place the parenthesis before the sentence period.
Source multiple authors in the text using the serial comma between each last name followed by the page number. For example, "(Johnson, Jamison, and Jones 24)." Again, if you list each author's name in the text along with the excerpt, include only the sourced page number in parentheses before the period.
Reference a work whose author is unknown by referencing the name of the document and the page number of the sourced text. Place shorter works in quotes and italicize longer pieces. Place the sourced page number after the title in the parentheses. For example, "("How to Make Widgets" 26)." Remember to place the sentence period after the parenthesis.
Cite Web pages using non-print source formatting. Use the author name or website name that corresponds to the Works Cited entry. Use partial URLs for the domain name if no other author name is listed. For example, "(ABC.com)." You do not need page numbers for such entries.
List multiple citations at the same time by separating each citation with a semicolon and putting both inside parentheses. For example, "(Jones 18; Mathers 210)."
Reference more than one work by a single author using abridged names of his works followed by the page number. For example, books entitled, "How to Grow Tomatoes" and "Growing a Beautiful Garden" by James Smith should appear as follows in the paragraph:
"Smith recommends growing Roma tomatoes for salads ("Grow Tomatoes" 79) and gives specific directions on how often to water them ("Beautiful Garden" 110)."
