I went to a really beautiful used bookstore called Loganberry Books (all the way on the East Side) for the first time a couple of weeks ago. The Northern Ohio Bibliophilic Society hosted a great lecture on the history of Pop-Up Books. I sometimes can't believe how many places there are that I've never been to in Cleveland!
Loganberry has a lot of events coming up, including the Edible Books Festival contest on April 1st. If you don't want to enter you can still come---for a $2 donation you can cast a vote and help eat the edible books. Categories are: Most Appetizing, Most Bookish & Most Creative.
Also, here's the link to the International Edible Book Festival.
