Let’s face it, if people didn't actually “judge books by their covers” there would be a lot of graphic designers out of a job. Like an album cover, a book cover is a crucial element of the reading experience.
A book cover is the first thing you see when determining whether or not to pick up a book. One of my favourite Facebook groups is Great Book Covers where people can, and do, post some great covers. My Blog is dedicated to some of the best book covers around :D
Hope you enjoy
