The “Online Writing Lab” (OWL) at Purdue University has excellent online guides to both MLA and APA. These websites also have complete, annotated sample papers that you can download and use as examples.
Formatting your APA Style Paper
There are three main differences between APA format and MLA format.
An APA in-text citation icludes the author's last name and the publication year. If you're quoting or paraphrasing a specific passage, you also add a page number. When there are two authors, APA styles separates their names with an ampersand (&), while MLA used "and". For three or more authors, list the first author followed by "et al." in both styles.
