"If you have a windows pc you may be interested in these: "Digital Hardbacks Exhibition Collection". These have been created for an
art project and are really good quality, innovative books (got spine and back covers too!). The selection is all pd, but some like Gibbon's Decline & Fall are really quite impressive. Have to mortgage your house though (luckily I live in a cardboard box).
