Writing a Bibliography: APA Format
Below are standard formats and examples for basic bibliographic information recommended by the American Psychological Association (APA). For more information on the APA format, see http://www.apastyle.org.
Your list of works cited should begin at the end of the paper on a new page with the centered title, References. Alphabetize the entries in your list by the author's last name, using the letter-by-letter system (ignore spaces and other punctuation.) Only the initials of the first and middle names are given. If the author's name is unknown, alphabetize by the title, ignoring any A, An, or The.
For dates, spell out the names of months in the text of your paper, but abbreviate them in the list of works cited, except for May, June, and July. Use either the day-month-year style (22 July 1999) or the month-day-year style (July 22, 1999) and be consistent. With the month-day-year style, be sure to add a comma after the year unless another punctuation mark goes there.
Underlining or Italics?
When reports were written on typewriters, the names of publications were underlined because most typewriters had no way to print italics. If you write a bibliography by hand, you should still underline the names of publications. But, if you use a computer, then publication names should be in italics as they are below. Always check with your instructor regarding their preference of using italics or underlining. Our examples use italics.
All APA citations should use hanging indents, that is, the first line of an entry should be flush left, and the second and subsequent lines should be indented 1/2".
Capitalization, Abbreviation, and Punctuation
The APA guidelines specify using sentence-style capitalization for the titles of books or articles, so you should capitalize only the first word of a title and subtitle. The exceptions to this rule would be periodical titles and proper names in a title which should still be capitalized. The periodical title is run in title case, and is followed by the volume number which, with the title, is also italicized.
If there is more than one author, use an ampersand (&) before the name of the last author. If there are more than six authors, list only the first one and use et al. for the rest.
Place the date of publication in parentheses immediately after the name of the author. Place a period after the closing parenthesis. Do not italicize, underline, or put quotes around the titles of shorter works within longer works.
