8.5x11 Hardcover for Amazon Sales
I'm wondering if there is a way to make an 8.5" x 11" hardcover for sale on Amazon like the softcover. I'm putting together an illustrated Bible and would like to offer a two-volume hardcover edition. I see there are no letter-sized hardcover distribution options at all.
Is it possible to buy my own ISBNs and affix them to the back cover and have them sell through Amazon as a POD edition?
