shinniku kara: "HLIM is a utility that allows one to track one's home library (currently supporting books, magazines, and CDs, with better magazine/journal support to come) using either barcode scanners or hand entry. Everyone's favorite feline-shaped scanner is supported, as is manual entry from the keyboard. CD title and track information is automatically looked up from the CD Index . Please note, that this is pre-alpha in quality, and only supports the PostgreSQL database, although any database with commit/rollback support should easily work. Also, documentation is currently thin." Check out their sf page  for download.
