I don't have a specific edition to offer, but you asked "why don't publishers publish more books with scholar's margins?" and the answer is because it's expensive. More white space means more paper and binding material, longer time for the print run, more customization on the press, heavier and therefore more costly to ship. Book publishing operates on a very thin margin so it's not cost-effective, especially when most consumers don't care about the extra margin space and/or aren't willing to absorb the costs in the purchase price.

What can consumers do to encourage publishers to change these practices? Be willing to spend the $80 for the scholar's margins instead of expecting to pay the normal $5 to $10.
