It's a LibraryThing
You know who you are.
You have hundreds of books stacked in piles or haphazardly on shelves. You love books and talking about them with other book lovers. Finally, what if you could easily catalog your library of books (no more messy "can't read my own writing" lists or tedious WORD document creations); connect with other book lovers who have similar libraries; or have recommendations made to you based on your library? No more "what if's"! Welcome to LibraryThing
Named by PC Magazine as one of the five best services of 2006 (Skype was another service named). "If you love books, and love people who love books, LibraryThing is for you. Start by using the service to catalog your book collection: Tag your books by topic, share your catalog with others, and then endlessly browse the titles that they have on their shelves." (PC Magazine, February 2006)
All you need to get started is to create a user name and password. LibraryThing allows you to catalog up to 200 titles for free; as many as you like for $10 (year) or $25 (life). Go ahead and take the tour today.
