Are book jackets redundant in the age of ebooks? Unsurprisingly, cover designer Peter Mendelsund thinks not - and here's his justification. Books do certainly help to decorate my living space - though Mendelsund would not approve of the fact that many haven't yet been read.
Some of the cover designs that accompany Mendelsund's article are brilliant, but inevitably publishers and/or designers aren't always quite so inventive or original - to the point that a few cover clichés can be discerned.
