Rarebooks.info was founded a little over two years ago with the aim of providing a comprehensive bibliography of books on rare books available for consultation on the internet.
Rarebooks.info so far comprises over 600,000 pages of key out-of-print bibliographies that can be browsed and searched transversally online. Important reference books available on line include Goff, Brunet, Sabin, and Lipperheide, among many others. These are not e-texts; they are scanned facsimiles of the actual books. It also offers a Reference Gateway, which provides bibliographic resources to books on books in more than 100 subject categories. Both the online facsimiles and the Reference Gateway are updated on an ongoing basis.
