APA Style (6th Edition)
APA (American Psychological Association) style is the standard method of publishing one’s writing in psychology as well as other social sciences such as nursing, anthropology, sociology, business and gender studies (APA, 2010, p. xv).
The following are highlights of some of the more important aspects of 6th Edition APA formatting, but do not constitute the whole of APA style. Please consult the manual (held on reserve at Boatwright Library) for a complete explanation of publishing guidelines.

In-Text Citations: General Guidelines
When to Cite
How many authors should you cite?
In-Text Citations: FormatOne Work by One Author
Include author’s last name followed by a comma, then the year of publication. If you are directly quoting an author, also include the page or paragraph number. Ending punctuation goes outside the parentheses.
The study aimed to measure the participants' preferences in different types of music based on their age (Baker, 2008).If you mention the author’s name in your sentence, then put the publication year immediately following the name.
Baker (2008) measured correlations between age and music genre preference.
One Work by Two AuthorsInclude both authors' last names and the article's date of publication in parenthesis. Separate the authors' last names with an "&" rather than “and.” Follow the same rules as with one author.
When citing more than two authors a second time, use the first author’s surname followed by “et al.” (which means “and others”).
Mean aggression scores for children exposed to aggressive adult models were significantly greater than those of children in non-aggressive or control conditions (Bandura et al., 1961).
One Work by Six or More AuthorsFrom the get-go, cite only the last name of the first author, followed by “et al,” "and others," or "and colleagues."
Nokes et al. (2012) found that nurses who used self-efficacy interventions for HIV patients showed a slight increase in patient adherence to retroviral treatment, though these effects were impacted by patient depression and lack of social capital.
Groups as AuthorsWhen citing an organization as an author, write out the organization the first time they are cited and list the abbreviation in the parenthetical citation.
A study by the National Institute of Mental Health (NIMH, 2003) found that...
No Author Specified/Anonymous Works and Legal DocumentsFor works with no listed author, or for legal documents, cite in text the first few words of the title. Use double quotation marks inside the parentheses for articles, webpages, or chapter titles; italicize titles of periodicals, books, brochures, or reports.
… total dollar amount (“A Systematic Review,” 2006)
When an author is specifically listed as “Anonymous,” use that as the citation name.
More Than One Work in the Same Parentheses
Order citations of two or more works within the same parentheses alphabetically, including citations that would otherwise shorten to “et al.” Separate works by a semicolon. Arrange two or more works by the same author(s) by date of publication.
(Ellsworth, 2002; Rylie, Short, Morgan & Christoff, 1996; Wang, Peterson & Morphey, 2002; Wang et al., 2007).
When citing more than one work by the same first author, add a suffix of a, b, c, etc. according to the order of works in the reference list.
Several studies (Rylie, 2002a; Rylie 2002b; Melsworth & Rylie, 2003a, Mellsworth & Rylie, 2003b) suggest...
In-Text Citations: Direct Quotes vs. Paraphrasing
When and how to use direct quotes (“”)?
When using direct quotes, always list in parentheses the authors’ last names, year of the article’s publication, and page number in this format:
(Purcell, 1997, pp.111-112) or (Purcell, 1997, p. 111)
Direct quotes less than 40 words
Put quotation marks around the quoted material, and incorporate the quote into your sentence. Try not to quote an entire sentence, as it makes the writing very choppy and usually comes off as lazy.If the quote is in the middle of your own sentence, end the quoted passage with quotation marks and put the parenthetical citation immediately after the passage, followed by any necessary punctuation. Then continue with the sentence as it would be normally.
Since the quote is in “the middle of this sentence” (Zhou et. al, 2013, p. 10), I would format the sentence this way.
If the quote comes at the end of the sentence, put the end quotation marks after the final word, insert the parenthetical citation, and end with the period (or exclamation/question mark, if you’re getting fancy).
Since the quote is at the end of this sentence, I would “format the quote this way” (Smith, 1992, pp. 10-12).Direct quotes more than 40 words
Place the quote in a freestanding block of text on a new line, indented ½ inch from the left margin. If there are subsequent paragraphs in your block quote, indent them another ½ inch from the first indent. Place the parenthetical citation at the end of the block, after the end punctuation. Double-space all of the quote.
Since my block quote had 40 words that you can’t see here, I’m going to end the quote this way. (Loving, 2000, pp. 111-115)If you mentioned the author’s name in the sentence with the quote
Only put the page number in parentheses if you already mentioned the author’s name; always put the year immediately following an author’s name when you refer to them in-text.
Since I’m mentioning Shields (2003) said “something related to psychology,” I only need to put the page number at the end of this sentence (p. 24).Directly quoting online material
In your parenthetical citation, give the author, year, and page numbers if possible. If there is no pagination, refer to the paragraph a quote was taken from. Use the abbreviation “para.”
Since I got this from a blog with no page numbers, “I’m going to cite using the paragraph number” (Doling, 2005, para. 4).Other notes for quoting directly
Reference List: Ordering Guidelines
Alphabetization Rules. Alphabetize by the author’s last name, followed by the first and middle initial. Remember that “nothing precedes something” (e.g. Carter, T. S. precedes Carters, A. K.).
Order of Several Works by One Author. Give the author’s name in the first and following entries.Single-author entries by the same author are ordered by year of publication.
Bargh, J. D. (1996).
Single-author entries come before multiple-author entries beginning with the same last name, regardless of publication year.
Cooke, R. D. (1995).
Reference List: Formatting Guidelines
References should contain the author(s') name(s), publication date, title, and publication information. For each cited work, list the authors in the order they are presented on the manuscript. The order of author names signifieswhat type of contribution they made to the work, and should not be alphabetized.If the reference is from an online source, include the DOI. This is a unique alphanumeric code assigned to online content, providing a permanent link to the information should the source url change. When a DOI is listed in your references, do not give any other retrieval information. The DOI should formatted like this: doi: xxxxxxx
If no DOI has been assigned to the content, then provide the home page URL of the journal, book, or report author/publisher. Do not add any punctuation to the URL, such as a period at the end or a hyphen across line breaks. You do not need to include database information, or retrieval date information unless the content material has changed over time.
Important note: When listing references, keep the first line left-aligned at the margin, and indent every line thereafter 1/2 inch. Due to online formatting restrictions we could not model the format here, but check the APA manual for an example.Books (not anthologies):
