APA citation style

Web pages

NOTE: For more information about electronic sources, please refer to the APA style guide to electronic references (restricted to Concordia users)

Web pages & non-periodical documents on the Internet
  • Include the author, title of the document, and if available, always include the date the material was updated or posted online. If the page may be changed or moved, include the date of retrieval. Include the URL of the document cited.
  • If there is no author, place the title in the author position.
  • If there is no date, replace the date with (n.d.) to signify that there is no date for the material.
  • Add a description of the source in square brackets after the title, if this is necessary to clarify the type of source e.g. [Bibliography] [PowerPoint slides] [Multimedia presentation]

Library and Archives Canada. (2008). Celebrating women's achievements: Women artists in Canada. Retrieved from http://www.collectionscanada.gc.ca/women/002026-500-e.html

  • If the source material is likely to change over time (e.g. wikis), include the retrieval date.

Geography of Canada. (2009, September 29). In Wikipedia, the free encyclopedia. Retrieved September 30, 2009, from http://en.wikipedia.org/wiki/Geography_of_Canada
