The publisher plans at least two more books based on materials found in 2013 by his widow, Audrey Geisel, and his secretary in the author's home in the ritzy seaside neighborhood of La Jolla in San Diego .
The author, whose real name was Theodor "Ted" Seuss Geisel, died in 1991 at the age of 87.
According to Random House, when Audrey Geisel was remodeling her home after his death, she found a box filled with pages of text and sketches and set it aside with other of her husband's materials.
It was rediscovered 22 years later, in the fall of 2013, by Audrey and Claudia Prescott — Ted Geisel's longtime secretary and friend — when they were cleaning out his office space.
They found the full text and illustrations for What Pet Should I Get?, among other work.
Seuss lovers were excited at the news.
