This site offers a variety of art market information. The main feature is a database with millions of records of prices realized at auctions for works by nearly 800,000 artists.

In the “Archives” section of the site, earlier sales records are found, including scanned pages from the Mayer auction index which was published from 1962 through 1987 (each annual volume must be consulted separately) and the Mireur dictionary of a selection of auctions held between 1700 and 1900. Some simple statistical data is offered for many of the artists. The site also contains summaries of annual trends, news stories, forthcoming sales, and other market information.

Many of the catalogues contain annotations indicating the prices obtained for individual works. The database also acts as a listing of libraries that have copies of these catalogs.
