Don’t people in the movies hide guns in hollowed-out books pretty regularly? (One that comes to mind is John Woo’s excellent Hard Boiled.)
A few weeks ago, there was a big "Friends of the Library" booksale where there were tons of books available for free on the last day of the sale. I probably should have picked up a couple of extra ones just to try this (I did pick up some to sell on Ebay, but there haven't been any buyers yet). Then again, I'm probably a little too lazy for a project like this.
