good luck. if it is a standard sized paperback, they used to make "paper back holders" that were essentially slipcovers for paperbacks, but were like a hard back book. i know that sounds weird, and if i could find mine, i'd take a photograph for you. but it had a slide for the spine, and the covers were hard like a hard cover book, but there were "pockets" for the front and back covers of the paper back.
