Build Your Very Own Online Library

I have been using Shelfari for quite sometime now. Actually ever since they mentioned it at RA in a day (a conference dedicated to reader's advisory) that I attended last year. I find it so handy to keep track of books I want to read or have read. I often see a book at the library and think I would like to read that someday. I use to write it down on a piece of paper which I would misplace and the completely forget what book it was but now I just log onto my shelfari account and add it to the shelf. It is simple enough to use but if can be hard searching for friends. The only way I have ever been able to add my own friends is by sending them invites and them joining. I think it is a fun site to check it. When you add books it puts them on a nice little shelf for you.
