Rightly or wrongly, we tend to judge books by their covers (ok, just a little bit). Why else would so much time be spent on their design? Some book cover designs are publicly declared great, making lists like the AIGA 50 Books/50 Covers, soon to be an exhibition in New York. Other times they go unnoticed, conveying the stories they contain so clearly they become invisible. And other times... they ruin the whole thing. This great collection of book cover before-and-afters shows just how crucial a cover can be – and highlights the success (or tragedy) of a redesign.
