APA Style Guide
The following examples are based on the 6th edition of the Publication Manual of the American Psychological Association. You can find copies of the Publication Manual in the library's reference and circulating collections, call number BF76.7 .P83 2010.
Key Changes in the 6th edition
DOI: Digital Object Identifier
The DOI provides a persistent link to journal articles. It can often be found on the title page of the article or in the citation information given in databases. You can find the article on the publisher's page for that journal by searching the DOI on http://dx.doi.org/.
APA no longer requires retrieval dates for electronic sources unless the source material may change over time (for example, wikis).
Reference List: Basic rules
- All recoverable sources cited in the text of the paper must have an entry in the References list; conversely, each source in the Reference list must appear in the paper.
- Center the title References at the top of a new page.
- Double space throughout your paper, including your reference list.
- Start the first line of each entry at the left margin, and use a hanging indent of 1/2 inch for subsequent lines within an entry. [In MS Word, use Paragraph>Special> Hanging]
- Use italics for titles of books and journals. Remember to carry the italics through the punctuation following the title (and volume number for journals).
- Two or more works by the same author(s) are listed by year of publication, oldest to most recent. For works published in the same year by the same author(s), alphabetize by title (excluding a, an, and the) and place a letter (a,b,c...) immediately after the date.
- If no author is given, list and alphabetize by the first word of the title, excluding articles (a, an, and the).
- Capitalize only the first word and any proper names in the title or subtitle of a book or article. A subtitle usually follows a period or colon.
- Capitalize all major words in titles of journals.
- End each citation with a period, except for entries ending with a DOI or URL.
- For electronic citations, do not insert a hyphen if you need to break the URL across lines; instead, break the URL before a slash or period.

Personal communication (personal interview, email, etc.)
Personal communications are only cited in the text of your paper, since they do not provide recoverable data.
J. Q. Public (personal communication, January 10, 2010)
or (J. Q. Public, personal communication, January 10, 2010)
A writer must document all information and ideas taken from others, whether quoting or paraphrasing that source. Use parentheses to mark reference citations within the text of a paper. Author(s) and date are used for paraphrased information. For direct quotations, add page numbers. When a work has no author, use the first few words of the title. Put quotation marks around the title of an article or chapter, and italicize the title of a periodical or book.
For short quotations (fewer than 40 words), enclose the quotation with double quotation marks, and place the author(s), the year of publication, and the page number of the quoted text in parentheses immediately at the end of your quote, preceding the closing punctuation.
For example, "James and Mary invented the formula after a great deal of study" (Thatcher, 1925, p. 23).
Or, Thatcher (1925) wrote "James and Mary invented the formula after a great deal of study" (p. 23).
For long quotations (40 or more words), place the quotation in a block, indented five spaces from the left margin. Do not use quotation marks. The parenthetical documentation follows the closing punctuation. Use double spacing, as in the rest of your paper.
As Baumrind stated:
The authoritative model of discipline is characterized by use of firm control contingently applied and justified by rational explanation of consistently enforced rules. Authoritative parents endorse the judicious use of aversive consequences, which may include spanking, but in the context of a warm, engaged rational parent-child relationship. (1996, p. 412)
