A few people commented on the book records poll to observe that they didn't see the point in keeping track of all the books they'd ever read. Is it a genre of life diary? Are people who keep track of books more or less likely to keep track of other things, like movies? Is it a form of collecting things which doesn't take up much space? Is it a tally for pride, each book a notch? Early life habit, once established, never altered?
For those of you who do so, why do you keep track (or want to keep track) of the books you read?
