To find biographical information on your author, use the following databases:
Biography in Context
This database contains full-text articles from a wide variety of subject encyclopedias and dictionaries, long and short, academic and popular. Also included are articles from a variety of magazines, newspapers, web pages, and even multimedia resources. You will find reviews of some of their works, and you could very well find some interviews.
GALE Literature Resource Center
This database also provides biographical information on authors, overlapping the one above somewhat. However, it will also get you into the more academic material, like literary criticism.
