They *don't* import all the information from Amazon, and they allow me to create bookshelves. There are three automatic bookshelves: Read, Currently-Reading, and To-Read. A book can only be on one of these bookshelves at a time. I also have the ability to *create* bookshelves, and all my books can be in as many bookshelves as I like. So, for example, I have a "library" bookshelf, which will contain all the books in my library (so every book should be in here, unless I screw up), and then beyond that, I can separate the books out based on which bookshelf they're in, which is basically a reflection of how I have them organized at home. It's quite useful, and so far it has found a couple of my books that should be harder to find in that they came from out-of-the-country. But still, no problems!
Beyond that, it has options to export my collection in .csv and whatnot, so I'll easily be able to transfer it to my home computer. I'm quite excited. ^_^ Oh, and did I mention it's free to create an account? :D
So yes...if I figure out how to do it, very soon there should be a live feed on this blog of the different bookshelves in my collection. I'm going to try to go for one showing the recently added books in my library, and the books that I'm currently reading. :)
