I just dug into LibraryThing a little bit. I am sorely tempted to spend the $25 on a lifetime membership. I maxed out the free 200 book entries already by just tossing the first few hundred items in my Amazon “purchased” list at it. (Turns out that I have bought 1209 individual items from Amazon. I had never checked that number before. Hmm. Then again, I have been doing all my Xmas shopping on Amazon for years).
