Citing Sources - APA


Watch Video: APA Citation Style for a quick introduction to APA citations.

See the APA Citation Style Guide for an excellent list of sample citations and guidance on doing in-text citations.

Consult the Purdue OWL Writing Lab APA Formatting and Style Guide for an overview of how the APA style works, both in writing your paper and in creating citations.

If you are interested in using a citation manager to gather your research source citations and format them as needed, see our Citation Managers guide.


You may also see the Citing Sources  page of the library site for a number of useful links and tips for information on how cite your sources and also some tools that will help you do so. And whatever you do, don't forget the ability to email yourself an APA, MLA, or Chicago citation from Articles & More and other databases. If you don't know how to do this, just ask me!

Here is the general MLA format to use when citing online images.  The rule is to fill out as many of the citation elements shown in the example (while understanding that some of them are difficult or impossible to identify):

Creator’s Last name, First name. “Title of the digital image.” Title of the website, First name Last name of any contributors, Version (if applicable), Number (if applicable), Publisher, Publication date, URL.

Here is the same sort of format to use in APA for citing an online image:

Artist or Author. (Year of image creation).  Description or title of image [Image format]. Retrieved from
