Collectors Weekly: How do you determine the rarity of a book?
Sanders: It’s the old law of supply and demand. From 1920s to the 1940s, Idaho Press and Caxton Press published a lot of Vardis Fisher’s limited edition, signed Morocco-leather-bound books, and they produced tiny editions of as few as 10 copies, but they’re not books that anybody cares about. They might be really hard to find, but no one wants them. So on a rarity scale, it’s hard to get much rarer, but you’re not going to have the same success selling even Vardis Fisher’s books versus limited signed Steinbecks and Hemingways.
