Citation Styles!
APA (American Psychological Association) style is the most common style for writing papers and citing sources in the Psych literature. MLA (Modern Language Association) style is more widely used in the humanities. You can use either in this course, though we are more familiar with APA, ourselves.
Here is a source for APA-style citation

The U. of Southern Mississippi also has a page on MLA style

Cindy Adams found this good general
guide to MLA style

It points to a useful (MLA-based) discussion of how and when to cite electronic
sources

The same folks have a sort of FAQ-based APA page
