How do I find information on an artist who is not famous yet?
You might want to find some magazine or newspaper articles about recent shows of his art. To find the magazine articles, your best bet would be Art Full Text. Newspaper articles might be available about the artist with reviews of his work. I would use LexisNexis Academic to find those. You might be able to find basic biographical information by using Biography and Genealogy Master Index. Biography and Genealogy Master Index is an index to a lot of biographical dictionaries. It can be tricky to use so if you need help ask a librarian.
