Whether it's those Star-Bellied Sneetches, The Lorax, or Sam I Am, everyone has a much-loved Dr Suess story.
But six of the author/illustrator's books are being stopped from any further publication because of concerns over their "racist imagery".
The announcement came on the late author's birthday and includes the books; And to Think That I Saw It on Mulberry Street, If I Ran the Zoo, McElligot's Pool, On Beyond Zebra! Scrambled Eggs Super! and The Cat’s Quizzer.
The discontinued titles include the first book Dr Suess, real name Theodor Seuss Giesel, ever published. The stories were pulled from print because of the racist way characters of Asian and African ethnicity are depicted.
Dr Seuss Enterprises, which represents the late author and illustrator, made the announcement saying, "these books portray people in ways that are hurtful and wrong".
Wellington's The Children's Bookshop owner Ruth McIntyre sells a range of Dr Seuss tales, including some of the works in question, but she says those ones have never been the most popular.
"One of them was published in 1937 and racial stereotyping was prevalent still at that time but it doesn't mean that it was right," she told Newshub.
"Scrambled Eggs Super - we've probably sold about one over the last year or two."
Instead, it's Dr Seuss's best-known stories that are still the favourites. Some of his other works are even celebrated for the way they address issues of equality.
Although six of his works are being pulled from print, Dr Seuss has a collection of more than 40 others - so there are still plenty of the author's other well-known titles available in bookstores.
