What is Dewey’s 24-Hour Read-a-thon? For 24 hours, we read books, post to our blogs, Twitters, Tumblrs, Goodreads and MORE about our reading, and visit other readers’ homes online. We also participate in mini-challenges throughout the day. It happens twice a year, in April and in October.

It was created by the beloved Dewey (her blog has since been taken down, so the link won’t work). The first one was held in October 2007. Dewey died in late 2008. We’re still saddened by her absence, but the show must go on. The read-a-thon was renamed to honor its founder in 2009.

Dewey’s 24-Hour Read-a-thon is hosted by Heather and Andi of The Estella Society, with help from volunteers.
