What is Dewey’s 24-Hour Read-a-thon? For 24 hours, we read books, post to our blogs, Twitters, Instagrams, Litsy, Facebook, 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. The next event is August 2, 2019! We start at 8pm Eastern. See this time in your time zone by clicking on the Start Times page. 

It was created by the beloved Dewey from The Hidden Side of a Leaf (her blog is archived at the Wayback Machine). 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 has been hosted by Heather of My Capricious Life and Andi of Estella’s Revenge, with help from scads of volunteers since 2013.
