A writer in the UK has released Abracadabra!, a free e-book about the Beatles’ “Revolver” album on the 40th anniversary of that LP being released. If you’re more interested in the public sharing of information than the Beatles, you might also want to check out “In the Public Interest: The Future of Canadian Copyright Law” which features articles by some of Canada’s leading copyright scholars and has also been made available for free under a creative commons license.
