There is a new site, outofprintmath, that is collecting information on which out-of-print books the mathematical reading public would like to see brought back in print. At the moment there are 67 books listed, many of them are surprisingly well-known. I had no idea so many classic texts were out of print. For example, Curtis and Reiner’s *Methods of Representation Theory*, Kuratowski’s *Topology*, and Riordan’s *Combinatorial Identities* are all out of print.

Timothy Chow tells the story behind the site’s creation here.
