Bijection Problems

I am interested in finding a source or a book that has a nice section of bijection problems. Problems should range in difficulty from easy AIME problems to easy Olympiad problems. I have the Art of Problem Solving, the Art and Craft of Problem Solving, and Problem Solving Strategies already.

Any help would be appreciated, thanks.
