This PDF was very worthwhile and is much appreciated. As a freelance illustrator (my clients include HarperCollins, PS Publishing, Pocket Books, Solomon Press, American Media, Fort Ross, Asimov's Science Fiction, and many other publishers and self-publishing authors), I am amazed at how rapidly things are changing in the book cover marketplace. Articles like this are a big help in keeping on top of things.
