From the ashes of H-LIS, the H-Net listserv devoted to more or less library history, comes H-INFO. An official description:
H-Info focuses on the interdisciplinary, international study of information and information institutions, broadly construed. It includes the foundations and history of print culture; reading and reception histories; the history and foundations of library and information sciences; and the history of libraries, archives, document-based cultural repositories, and other information institutions.
The best part is that H-Info, along with all other H-Net lists, is available via RSS!
