APA Style Guide: Articles

This guide is designed to help students learn about APA style and cite sources for their research.

DOI

A digital object identifier (DOI) is a unique code assigned to an electronic publication so that it may be located on the Internet through a persistent link. It is recommended by the APA that when a DOI is available, it be included for both print and electronic publications.  If a DOI is included, no additional Internet retrieval information is necessary.

Not all publications have a DOI, but you can look up an article on the CrossRef website to find the correct DOI to include in a reference.

Hint: Think of a DOI as being an article version of a book's ISBN.

Quick Tips

In general, only the first letter of the article title and subtitle are capitalized, with the exception of proper nouns.

The first letter of every significant word in the journal, magazine or newspaper title is capitalized, with the exception of articles and prepositions such as an, the, of, in, etc.

The volume number for journals is always italicized.

The issue number is provided in brackets after the volume number only if the journal is paginated by issue. If available, both volume and issue numbers are included in references for magazine articles. 

Articles

Information required for an article reference includes:

  • Author(s)
  • Year of publication for journals; year and month for magazines; year, month and day for newspapers
  • Title and subtitle of article
  • Title of journal, magazine, or newspaper
  • Volume number of journal or magazine
  • Issue number of journal or magazine (if paginated by issue)

Newspaper Article (No Author's Name Provided):

Examples of In-Text Citations:

Parenthetical citations:
Global cooling can be seen as the result of natural cycles, whereas climate warming may be caused by the accumulation of greenhouse gases in the atmosphere due to human activity such as industrial pollution and land use (Vogel & Lazar, 2010).

The destruction of maple trees due to the double threat of long-horned beetles and global warming would have financial repercussions specifically for "tourism, forestry and the $15 million annual maple syrup industry" ("Maple Trees," 2012, p. A7).
 

Narrative citations:
According to Botkin et al. (2007), there is no reliable way to forecast rates of extinction.
