I collect more things that I care to admit to, and if I had the time, I might just sign up to Squirl which allows you to catalog not just books like LibraryThings but pretty much anything. For insurance purposes, this would be a good thing, but I haven’t got the time to catalog everything beyond what I did with Intelliscanner when I moved some 19months ago and truth be told, I don’t want to. I like being organised but when it comes to stuff like this, a little disorganization is not a bad thing. Particularly is you don’t want to really know how much you are really spending on the junk collectibles you’ve purchased.
