One of the reasons why Adams switched to Simon & Schuster was that Grosset & Dunlap did not like this move, while Simon & Schuster agreed to it. To collectors of Nancy Drew and Hardy Boys books, books in the original series published at Simon & Schuster are called "digests." This is due to the books resembling digest-size paperbacks, differing from Grosset & Dunlap's hardcover books. These books feature increasingly contemporary cover illustrations and some books have multiple versions of the cover art. Though formatted differently from the original 56-volume series which continued under Grosset & Dunlap's control, these new books were published under the Nancy Drew Mystery Stories banner. In 1979, the Nancy Drew books began to be published by Wanderer Books Simon & Schuster in paperback format.
