Oxford Art Online
A good starting point. Includes the Benezit Dictionary of Artists, the Grove Dictionary of Art, the Oxford Companion to Western Art and the Encyclopedia of Aesthetics.

Use the bibliographies, footnotes and references from your course readings to find sources about your artist or architect.
- Published Bibliographies
Search your topic and add the word "bibliography" to find a list of published works. Example: "Frank Lloyd Wright" + bibliography
