I registered on this site just to review this program. It's exactly what I was looking for, and you can't beat the price (free). Not exactly as intuitive as it could be (took me a while to figure out how to sort by fields other than the title), and the search is still a little wonky (it would not come up with the common, mass-market paperback edition of a popular book on a title search - I had to use the ISBN #), but overall it's already proved to be very handy.
