Cuz here 's the buried lede in plain language : Dr. Seuss books are going digital . Yes , you 'll have to make sure your `` Green Eggs and Ham '' does not become spam . That title is one of the 41 children 's books by Theodor Seuss Geisel to be released in three waves this year -- beginning September 24 , according to Random House Children 's Books , which also publishes the print editions . According to a news release , more than 600 million of Geisel 's books have been sold worldwide .

A second wave of titles will be released in e-book form on October 22 , and a third on November 5 . Prices will range from $ 7.99 to $ 10.99 . Geisel , who won the Pulitzer Prize in 1984 , an Academy Award , three Emmy Awards , three Grammy Awards , and three Caldecott Honors , wrote and illustrated 44 books for children . The e-books are the latest in a series of Seuss-related products that have appeared since Geisel died in 1991 , including toys , clothing , animated stories , a Broadway musical and a Florida theme-park attraction . `` Nothing is static , '' his widow , Audrey S. Geisel , told the History Channel in a documentary . `` There 's only two directions it can go : onward and upward , or it can go downward and oblivion . And if it takes selling cookies or figures or T-shirts or this or that or the other thing , so be it . ''
