Common APA Errors by Citation Tools

Look for These Common Errors

  1. Uppercase is used in article titles. Except for the first word, the first word following a colon, and proper nouns, all words in article titles should be lowercase.
  2. The volume number of the journal should also be italicized.
  3. Extraneous information is included (e.g. Cover Story).  Delete this information.
  4. A DOI is not included.  If no DOI is listed, use CrossRef free DOI lookup to see if the article is assigned a DOI. If no DOI is assigned list the publisher url.

When in doubt, check with your course instructors about their preference for listing citations in your references page.
