A "seussologist" in Massachusetts came across a collection of what he calls "lost stories."
Charles Cohen found a number of works written by Seuss that appeared in magazines back in the early 1950s.
He knew it was something he had to share with the world.
"I thought I'd found this lost treasure, and I felt like a shame that I was able to enjoy them and nobody else was able to get the same pleasure I was having," said Cohen. "I'm so pleased that these things that nobody knew about will hopefully soon be globally recognized."
Cohen said the book contains message stories, such as "How the Grinch Stole Christmas." Others include new species of Seuss characters.
"The Bippalo Seed and Other Lost Stories" is set to be released Sept. 27.
