Social Networking for Bookworms

From The Wall Street Journal:

"If bookcases are a way to casually display interests dear to the owner, the Internet throws open the doors on reading habits. Social-networking and book retailers' sites are already rife with lists of readers' favorite material, allowing people to compare notes on taste and compatibility.

But for Tim Spalding, a computer programmer and bibliophile, listing a few titles in an online profile isn't enough. He sought a way to catalog his entire book collection -- and to check out what was lining other people's shelves."
