The funny thing is that I found a DRM-free copy of the book you mentioned on the internet in less than a minute. PDF or ePub, your pick; probably converted from the same source.

Whatever these publishers are trying to do, they're only hurting their honest customers. It's trivial to find popular eBooks online regardless of library licenses and DRM usage yet honest people's lives are made so incredibly difficult for no good reason.
