Theodor Seuss Geisel, better known to the world as Dr. Seuss, is alive and well in libraries and homes across the country, even though he died over two decades ago. Now, he will be back in print again with a new collection that brings together some of his rarest works.

Random House announced a new collection that will be out on Sept. 9 called Horton and the Kwuggerbug and Other Lost Stories. According to USA Today, the book features four short stories that Seuss wrote for Redbook magazine in the early 1950s. While they were published then, they have not been seen since. They have never been published in picture-book form.

The title story features the star of Horton Hears A Who! and was first printed in 1951. As The Guardian points out, another story in the collection stars a Grinch, before another Grinch stole Christmas, and was first published in 1955. One 1950 story features Marco from And to Think That I Saw It on Mulberry Street (1937).

“For the most part, those magazines were tossed out when the next month's issue arrived and the stories were largely forgotten,” Charles D. Cohen, a Suess expert, writes in the book’s introduction. The stories are “fresh encounters with old friends and familiar places,” he notes.

Seuss died in 1991, but fresh collections of his work have continued to appear. The new Horton book follows 2011’s The Bippolo Seed, which also featured Redbook stories.
