Judge A Book... by its Cover: "I love books. I love the smell of 'em, the feel of 'em, and I love the look of 'em. In fact, I even like to read them, but that's another story. The main preoccupation of this site is the covers of books. Mainly books I've picked up in charity shops, or at carboot sales or jumble sales, even some that I've found on the ground."
The link above is to a site maintained by Jim Barker, clearly a collector after my own heart. He's the brains behind Planet of the Sardines, which I've mentioned previously. Judge a Book has the covers organized by category, and as Jim says, "Here you will find hard-boiled detectives, scantily-clad floozies, unlikely space-ships, grotesque aliens, bizarre religious images, beatnik shockers, hell's angels, skinheads, barbarian heroes, and horrifying monsters... among others." Check it out.
