Encyclopedia of World Art - Ref N 31 .E56
Offers scholarly and thorough articles on artists, movements, media, periods, national traditions, and so on. Each volume has a section of plates in the back. There is an index to the entire set, as well as supplementary volumes presenting newer information. Though more dated than the Dictionary of Art, above, this set remains useful, particularly for its thorough indexing of plates, making it a good source for locating images of art works.
