If you are asked to use APA format for a paper, the book to consult is the Publication Manual of the American Psychological Association (5th edition), which the American Psychological Association has recently updated. Citing electronic sources was a major part of this update as these types of sources are increasingly common in research within the social sciences. Below, you will find some examples of these updated citation styles.

The documentation style of the American Psychological Association

The Publication Manual of the American Psychological Association offers complete guidelines for manuscript style and citation in APA, the documentation style of the social sciences. This handout illustrates the most commonly used types of sources with examples drawn from the Publication Manual of the American Psychological Association, 4th ed. and The Bedford Handbook for Writers, 4th ed. If you have a source not illustrated here,

Points to remember about APA:

 APA uses an author/date style of in-text citations, referring by the author's last name to the References page at the end of the text.

 All references are double-spaced.

 For manuscripts submitted to journals, APA requires the form illustrated here (with the first lines of reference entries indented and subsequent lines flushed left). The hanging indent form (first line flushed left, subsequent lines indented) is customary for student papers. Check with your instructor to determine which form is appropriate.

 Capitalize only the first word of an article title and of the subtitle, if any, and any proper names. On the references page, do not underline the title of an article or place quotation marks around it.

 Capitalize significant words in the title of a journal.

 Capitalize only the first significant word and only proper names within book titles. Capitalize the first significant word of the subtitle, if any.

 Because personal communications (letters, memos, telephone conversations, interviews) do not provide recoverable data, they are not included in the reference list. Cite personal communications in text only. Example: (K. W. Schaie, personal communication, September 28, 1993)
