I like to keep track of my reading. I record all the books I read online, give a short review, and I regularly recommend the best stuff to anyone who seems at all interested in reading. Since late 2005 I was using an online application called Reader2 to record all that info, but I was never very happy with it. There was lots of stuff it wouldn’t keep track of and sometimes when it did ask you for stuff it would give you a very restrictive set of options. For example, if you would like to label each book fiction or non-fiction Reader2 would let you label something as fiction but had no non-fiction label. The closest label I saw was “documentary”. When was the last time you read a documentary?
I had asked the Reader2 author about allowing generic tagging but that was out of the question and when it went for a really long period with no big improvments I finally decided it was time to jump ship to something else. Where I landed was LibraryThing. It seems to be getting upgraded regularly and while there are probably enough features to choke a horse, I was able to figure out enough fairly quickly to get all my books, ratings, and the short reviews I had for each moved over. If you’re looking for a place to keep track of your reading and (optionally) share it with your friends, LibraryThing looks pretty good.
