What is APA Format?

APA stands for American Psychological Association.  APA Style is used to write papers and cite sources in the sciences such as nursing, psychology, and social sciences.
The purpose of citing sources is:

  • To avoid plagiarism
  • To give credit to the original creator of information you used in your research paper
  • To inform readers of the sources you used

If you are asked to use APA format, be sure to consult the APA Publication Manual (6th edition), available at the MPC Library.

Online Access (Spring 2020) to the Publication Manual of the American Psychological Association!


Many of the MPC databases provide MLA and APA citation formatting, but these are not always accurate.
