So I was at BlenderWiki a few days ago, and noticed that there was a link entitled Esential Blender. So I clicked on it. On this page was a zip of the entire book in .txt, and zips of all the images (except for chapter 1).
How does this work out? Wouldn’t there be some form of copyright issues? And if it is correct, then why hasn’t anyone ever made a .pdf (With the pictures put in place) of it?
