I'll echo those recommending Libib, but that's assuming, to Vivian's point, you're treating the book collections as a library collection and not a museum collection. My institution has used Libib for years for our reasonably small (~ 2,000 books) focused lending library. I found it infinitely easier to use than Library Thing.
We do have a few books accessed as part of our collection, but those remain separate from Libib and under our normal archival collecting process. I would not recommend Libib for that purpose.
