Dewey’s 24-Hour Read-a-thon is an international reading challenge. For 24 hours, participants read books, post on their blogs (and/or social media accounts like Facebook, Twitter, Goodreads, etc.) about their reading, and visit other readers’ blogs. Participants also take part in mini-challenges throughout the day and win prizes. There are five ways you can participate: Reader, Cheerleader, Mini-Challenge Host, Organizer and Prize Donor.
