craftgrrl | Old encyclopedias / brainstorming

Hi - I've been lurking in this community for quite some time, but this is my first post. I've recently come into possession of an old partial set of encyclopedias. I plan on using some of the pages for wallpapery type stuff (I haven't tried to figure out how to do that yet - but all in good time), some of the pictures for framed pictures and them some of the books I'm planning on hollowing.
Thing is - there are LOTS of them and even after going through with my plans, I'll still have lots of them left. Any ideas on what I could do with them other than the ideas I've already come up with? Thanks for your help!
