This is pretty cool! LibraryThing, where I catalog all my books -- because how else am I going to keep track of them? -- just came out with a spiffy new interface that makes searching through a collection of books really simple and easy. It's mainly aimed at lending libraries of various kinds, and they have to pay a fee to use it, but they've made it available for free to people who use the site to catalog their personal book collections. Which means that if you want to search through my books, say to check if I have a particular volume you'd like to borrow or to make sure I don't already own a book before you get it for me for Christmas, you can go here and pretend I'm an actual library!
