Fast Company recently profiled Penguin books cover designer Coralie Bickford-Smith and The Atlantic ran a piece on their hand sewn covers that will be releasing soon.
Penguin seems to be the leader in this area, but as word spreads and interest grows in collecting books as works of art, not just to read, the growth may be significant.
