I signed up for a lifetime account with LibraryThing recently and ordered the :cuecat scanner which arrived yesterday. So I spent the evening scanning in my collection. So far I got my hard covers and trades scanned in. I'll probably get to the mmpbs this weekend.

Its a pretty nice inventory system, and is customizable. I really like it. Its free to try $10/yr or $25 for life. That's cheaper than many other software based applications I've seen. Out of over 200 books I only had trouble finding a couple, mainly with non US editions.

Here are the links.
