With everyone being a book lover on here, I figured I'd share with you a place that allows you to keep track of your entire book collection. You can tag your books, sort, search, filter, share, review, wishlist, etc. Best of all it's free!
BiblioPhil - http://www.bibliophil.org
I bet some of you even know about it already. It seems that bibliophil went through some hard times, and looks like all the bugs are fixed now.
All in all, I think that bibliophil would only compliment this LJ Community. So I'm hoping that this post is helping, rather than spamming.
