College of San Mateo Library Director Lorrita Ford asked me if I was familiar with Book Cakes. Although I made a good guess, I hadn't realized that there were books on how to make them, images of great book cakes, and more. I looked up "Book Cakes" and found a few sites that showed me more information on them. Love the idea! Bet they are popular with some book clubs.
Here are some related articles and books:
Gingerbread Library Fundraisers (Conshohocken, PA), but not book cake contests. This could be a yummy contest and PR opportunity.
