In 1979, The Stratemeyer Syndicate switched publishers, going from Grosset & Dunlap to Simon & Schuster. In 1984, The Stratemeyer Syndicate was sold to Simon & Schuster. The Digest Series began in 1979, after the switch. It ran for 24 years, ending in late 2003, and consists of 119 books. The books were no longer written under the same format. For the most part, the Digest books are approximately 140-150 pages and 15 or 16 chapters long. They were written by many different ghostwriters and used several different illustrators.
The books were mainly printed as paperbacks, but several of the earlier volumes were printed in the yellow hardcover format, used in the Classic series. An example of one of these books is shown below.
