cool. yes, IP laws are nonsense, of course, but there's also the fact that the publishing industry is highly exploitative. I wrote a few books, but publishers know that academics have to do that for their CV, and they use that mercilessly. I get a notice every year that cumulative royalties or all my books combined come to about 10 Euro. Of course, academic books don't sell that much, but percentage-wise, it's still peanuts. If you're unknown, they TAKE money from you to sell your book and keep the money; if you're a bit better known, they do it for free and pay you 2-5% of revenue from the 401st or 801st book on; very rarely do you get paid from the get-go. So yeah, go search for your books wherever you like. The authors gain a lot more by exposure and virality of the book than they ever would from the sales price, unless you'r e George R.R. Martin or something (and even here, the virality of the book made him a lot more money through licensing than book royalties ever did).
