Not sure about the title just yet, but the first thing that popped in my mind were the bulletin boards a lot of our coffee shops have. They usually have push pins and people randomly hang when a band is performing, apt for rent, etc.
You might tie that into book recommendations by allowing the students to randomly put their own creations up so it's unique like a coffehouse. Some could post recommendations on a sheet of paper, sticky note, and computer print out, or index card so you have a variety. As a organize freak this would drive me crazy, but I would do it because the kids would love the freedom.
Maybe you don't have to include the word "book" in the title.You could simply explain that the Cafe' News (or message) board, The Bean Bulletin, or The Peer Post should be used for book recommendations.
If you want to include book in the caption, what about calling it the Book Nook or Book Bulletin?
My creative juices are a bit off today as it is 100 degrees out and I have been in it for couple hours.
