I can't wait to get a copy of Jason Thompson's brand-new project, Playing with Books: The Art of Upcycling, Deconstructing, and Reimagining the Book. Thompson, the founder and creative director of Rag and Bone Bindery, has long kept a blog featuring the best book and paper artists. Now he's edited a book art book, and it looks great. I mean, it has a section on "shaping books with power tools" - what more do you need??
I always love art pieces made with books and have done a few experiments of my own, but I can't get over feeling guilty for ruining a good book. Can't wait to see Playing With Books, though.
Ahava - if you locate used books with damaged bindings, it can help with your guilt. :) I once got an illustrated 19th cen. book on ebay that had been used to press flowers, and was so old and warped and torn, it wasn't readable as a book anymore - so i could cut it up without feeling bad. :) But yeah, I end up keeping most old books I buy intact.
