I would like to compile a bibliography of medieval art. In part it serves as a wish list, in case I ever win the lottery. This is a start, these works are surveys of the entire Medieval period. The only ones I am familiar with are the Calkins, which I own; the 1st edition of the Snyder, which was my Medieval Art textbook at OU; and the Stokstad which I have seen in the library. I quick look via Google at a few syllabuses for Medieval Art surveys seems to show the Snyder and Stokstad are the two most common textbooks in use. I hope to get my hands on the all of these in the near future. I f I do so, I may repost an annotated version of this.
