Citing Your Sources: Preparing a Reference List

This guide will help you cite your sources properly and avoid plagiarism in your writing

Formatting a Reference List

APA style requires two elements for citing outside sources: parenthetical (in-text) references, and a references list. Together, these elements allow your reader access to the sources you consulted.

For the system to function, all authors cited in the text must appear in the references list, and all authors listed must have been cited in the text.

Formatting the References List: If you need more detailed information about the APA style's requirements for the references list, consult the Publication Manual of the American Psychological Association (6th ed., 2010), or your course instructor.

General guidelines: Type the word 'References' at the top of a new page, centered. All entries should be double-spaced, unless your assignment instructs you otherwise.

Appearance of Entries: Although the current Publications Manual advises standard (five spaces, first line) indentation for a references list, this is primarily designed to make typesetting easier; the typeset version will have hanging indents (first line flush left, the following lines five spaces indent). If your final version will be turned in for a grade rather than publication, we recommend that you use hanging indents for enhanced readability. We have formatted our sample references list with hanging indents.

Capitalize only the first work of titles of books and articles and the first word after a colon.

Use a comma to separate: 1) surnames (i.e., last names) from initials; 2) a newspaper title from p. or pp.; 3) a journal title from a volume number; 4) a volume number from page numbers; 5) when given, an issue number from page numbers; 6) (Ed.) from book title; 7) city of publication from state.

Don't panic! The examples below will make this clearer!

* APA emphasizes using the DOI (Digital Object Identifier) when referencing articles. Unlike URLs which may change over time, the DOI is unique to an individual work. Not all publishers participate in the DOI initiative; as a result, an article may or may not have a DOI assigned. Usually only journals (primarily scholarly/research), and some online books—are assigned a DOI. Magazines, newspapers, newsletters, and most online documents/reports do not have a DOI.

Work Discussed in Secondary Source

Use secondary sources sparingly, for instance, when the orginal work in out of print, unavailable through usual

sources, or not available in English. Give the secondary source in the reference list; in text, name the original

work and give citation for the secondary source. For example, if Allport's work is cited in Nicholson and you did

not read Allport's work, list the Nicholson reference in the reference list. In the text, use the following citation:

Allport's diary (as cited in Nicholson, 2003).
