OK, in spite of the potential boring factor, I tried it. While I am not in the least interested in cataloging my entire home library, I found that Yes, LibraryThing is not only fun but useful! I'm going to add my book club's history of books read, along with books we come across that we might want to read. So when we plan in the Fall, our list of suggestions will be ready-made, and everyone can see the covers, TOC, and Amazon reviews at least.
