Generally I'm not one to rave about social networking sites, but for an avowed word-nerd such as myself, Librarything is a treasure trove. It's basically Last.fm for bookworms! Godly. The site's aim is simple: allow marathon readers to catalogue their own personal bedside libraries, organize the titles by tag, and connect with other readers who share similar tastes. Once you've got a few names in your library, you can really start having fun--try clicking 'tag cloud' or 'author cloud' to see what you're topheavy on, visit the Author Gallery to peruse writerly visages, or feel important because according to the 'Fun Statistics' page, you're the only one with a copy of The Game of the Foxes in your house.
Heaven. Somehow it's just so reassurring to know that there are exactly 184 other Librarything users who own The Courtship of Princess Leia. 16 other IP addresses are fans of Lonely Planet's British Phrasebook, while the owners of the Harry Potter series are in the high 7000s. And these numbers are just for today; who knows how many more there might be tomorrow?
This site restores some of my faith in the human race as readers. Maybe libraries will not become defunct after all--because these, these are my people.
