Since a majority of your information must come from printed text, you are going to have to visit a library at least once. To save yourself time, search the catalogues to see what is available before you go. Write down the title and call #s. It will save hours if you do this before you go to the Library. Don’t be afraid to ask for help while there. In fact, if you go to MASS Art Library, they will be expecting you!
Your Best Bet for Art Research:
Mass College of Art (Green Line, E train near Northeastern & MFA)
Boston Public Library (Green Line, Copley Square)
I have also had students go to the Museum of Fine Arts, Boston and be let into the special archives room.
Or Google any other college library and browse its online catalogue before making the trip. You can call them and see their policies. Most are open to the public (except Harvard) but you will probably not be able to check out books.
Some good Art Magazines with websites.
Libraries will often have these archived. But you can see which issues, if any, relate to your artist before you go searching:
It is also a good idea to Google your artist and see what scholarly work and books you can find. It is helpful to have a list of title from which to choose to look for before you go to the library. The more time you can save yourself, the more productive you will be.
