The best library resource for locating your author's biographical information is Gale Literature (also linked below). Search by their name to find credible articles from a variety of sources.
Search for articles using the title of your selected story, the name of your selected author, and keywords to describe topics, themes, and theories.
Limit your search to Scholarly/Peer-Reviewed/Academic journal articles by checking the box under "Limit your results" in EBSCO. Note: JSTOR is a scholarly journal database, so there is no extra check box for this type of publication.
