Refer to the examples below based upon the APA Style Guide, 5th edition.
It is customary when directly or indirectly using or referring to another person’s words, ideas, and opinions to cite the source from which it came. With the existence of an increasing number of electronic sources, there is a need for guidance on how to cite these sources properly. There are several well-known citation sources available, such as the MLA and APA style guides. Many journals also have their own citation instructions for prospective authors to follow, so when writing for publication, follow the individual journal’s "Instructions for Authors."
Below are some common citation examples for electronic sources taken from the 5th edition of the APA Style Guide.
