I think this a very sad development. Thanks to this vast archive I've found some of my favourite books. Even books that are frowned upon, but definetely good. The Green Book by Muammar Ghaddafi, Il Principe (The Prince) by Nicolo Macchiavelli and a very good scan of the first edition of The Anarchist Cookbook by William Powell. :-)
It's a big shame that publishers are like this. Greed.
