I've been testing this software as I need an app that includes more collections (I'm user of dvdpedia and need to store books and video games too so don't want to pay for different pedia apps).

Librarian is a clean software, beautiful, easy to use, but from my point of view, it lacks on more options to grab info from the web (it only uses Amazon as search) an is painful when your database is higher than ridiculous 50 mb.
I import my dvdpedia database to Librarian. It was successful including pictures, and was about 1,200 films. When trying to open it Librarian excuses its bad memory performance on a database bigger than 50 MB and opening and working with that database is painful as hell. My iMac is intel, two years old with 3 Gb of Ram and Leopard.

I think it's a needed improvement from Koingosoft because Librarian is great, really , but only if you have a small database is worth paying.

thanks.
