APA (American Psychological Association) is one of the main styles of academic writing used in the United States. Two other popular styles are MLA (Modern Language Association) format and University of Chicago format. When you cite references in APA style, the format of the reference is dependent largely on the type of material the information comes from. For example, you will cite a booklet in a bibliography entry differently than you would cite a regular book, an encyclopedia or a website.
Type the name of the author or organization that produced your booklet, followed by a period. If the author is a person, type the last name and first initial. If the author is an organization, type the name of the organization. For example, a pamphlet relating to multiple sclerosis may be authored by "The National Multiple Sclerosis Society."
Type the year of publication for your booklet in parentheses, followed by a period. The period goes outside of the parenthesis.
Type the exact title of the pamphlet in italics, followed by a period. Following this information, cite the edition number of the booklet in parentheses (if applicable).
Type the city and state (abbreviate the state using the two-letter postal abbreviation) where your booklet was published, followed by a colon. Follow with the name of the publishing house that published the booklet.
