APA-4b: APA list of references

APA-4bAPA list of references.

As you gather sources for an assignment, you will likely find sources in print, on the Web, and in other places. The information you will need for the reference list at the end of your paper will differ slightly for some sources, but the main principles apply to all sources: You should identify an author, a creator, or a producer whenever possible; give a title; and provide the date on which the source was produced. Some sources will require page numbers; some will require a publisher; and some will require retrieval information.

Directory to APA reference list models

General guidelines for the reference list

Section APA-4b provides specific requirements for and examples of many of the sources you are likely to encounter. When you cite sources, your goals are to show that the sources you’ve used are reliable and relevant to your work, to provide your readers with enough information so that they can find your sources easily, and to provide that information in a consistent way according to APA conventions.

In the list of references, include only sources that you have quoted, summarized, or paraphrased in your paper.

General guidelines for listing authors

The formatting of authors’ names in items 1-12 applies to all sources in print and on the Web—books, articles, Web sites, and so on. For more models of specific source types, see items 13-69.

1. Single author

image

2. Two to seven authors List up to seven authors by last names followed by initials. Use an ampersand (&) before the name of the last author. (See items 3-5 for citing works with multiple authors in the text of your paper.)

image

3. Eight or more authors List the first six authors followed by three ellipsis dots and the last author’s name.
