April fools' day is also the perfect day to eat your words and play with them as the "books" are consumed on the day of the event." This is global banquet, in which anyone can participate, and is shared by all on the internet and allows everyone to preserve and discover unique bookish nourishments.
The International Edible Book Festival is a creation of Judith A. Hoffberg and Béatrice Coron. The late Hoffberg got the idea over a Thanksgiving turkey with book artists in 1999, and Béatrice created Books2Eat website where despite the distances everybody can enjoy worldwide creations. They contacted friends and colleagues, and their first event took place in 2000. Since then the festival continues as an annual sensation.
The University of Texas, Austin, has a great website about their Festival.
Check out the internet for a Festival at a library, university or bookstore near you.
