JSTOR, the non-profit—but unfortunately not free for people not connected with a member university or institution—digital archive of journals and monographs from across the humanities, social sciences and sciences, has launched a new initiative: JSTOR Auction Catalogs. It is “a pilot project funded by The Andrew W. Mellon Foundation to understand how auction catalogs can be best preserved for the long-term and made most easily accessible for scholarly use. Auction catalogs are vital for provenance research as well as for the study of art markets and the history of collecting. This prototype site is open to the public through June 2010. If you are interested in this content and the importance to art research, we encourage you to try the site and take the brief survey linked below.” For starters, they are digitizing “a small set of english [sic] language auction catalogs dating from the 18^th through the early 20^th century.” Try out the search engine, browse through the vintage catalogs and give some feedback!
