Here is an example of an APA citation of a printed text:
Jones, M.W. (2000). Genesis and mimesis: The design of the arch of Constantine in Rome. Journal of the Society of Architectural Historians 59. 50-77.
When citing sources from the Internet, stay as close as possible to the form above for printed texts, but add at least a URL and a date on which you viewed the source. The following checklist gives a thorough listing of information you should include, if available, and gives the information in the order in which it should appear in your entry.
1. Author(s) or editor, alphabetized by last name, followed by a comma and first initials.
2. Within parentheses: year of publication, followed by a comma and month and day of publication for magazines and newspapers--OR note the latest revision date, followed by a period after the parentheses.
3. Title of the short work with no quotation marks and with only major words capitalized, followed within brackets by the total number of paragraphs of the work (if this information is available).
4. Title of the longer work, italicized, followed by a comma.
5. Volume number (if one exists) of the book, journal, or work, in which the short work appears, followed by a comma.
6. Page numbers--only as the short work appears in a printed version, if available. When the periodical has no volume numbers, use "pp." or "p." for indicating "page"; if the journal has a volume number, omit the "p"s and just use numbers. A period follows the page numbers.
7. Date of YOUR accessing the source, starting with the word "Retrieved," followed by the source, such as the World Wide Web, and a colon.
8. CRUCIAL: The URL, giving the "address" of the source. Provide complete information.
NOTE: Not all the information above is necessarily available: just note what is available to you.
Schematic illustration: Author's Last name, First Initial(s). (Year published, month day). Title of short work. Title of longer work, Vol. #, p. #s. Retrieved when from where (probably WWW): URL
