Overview: APA Style

APA Citation Basics

The OWL (Online Writing Lab) website from Purdue University provides some great examples of citing in APA style and in MLA style (look at the left side menu on the page for the links to examples for various source types).

There are certain basic things you need to cite just about any source, using just about any format:

  • The AUTHOR (or creator) of the work.  This may be one person, many people, or a group or organization.
  • The TITLE OF THE WORK itself.  For example, the article title, the book title, the chapter title, etc.
  • The JOURNAL or the PUBLISHER or the ORGANIZATION RESPONSIBLE FOR THE CONTENT .  For an article, you include the name of the specific magazine or journal.  For a book, the publishing house. For a website/webpage, include individual authors, if they are noted. Otherwise include the organization name.

There are also certain things that must be included for specific types of works.  For example, for an article or a book chapter, you would provide page numbers.  For a website, you would provide the URL.

The moment when you are most likely to have easy access to all of this information?  When you find it in the first place.  Know then what you need to take note of to cite it effectively later.
