A number of bloggers have been trying to locate the best social networking sites for books.

As book review outlets decline and publicity budgets shrink, these websites will become increasingly more important for the publishing industry. Editor Angela James initiated the conversation, and then the Dear Author blog built an online poll comparing the three major social networking sites for readers.

Here are the results so far, after 206 votes: 27 percent use Library Thing, 20 percent use Shelfari and 25 percent use GoodReads. 45 percent don't use any social networking site for books. Follow this link to participate in the poll.
