Dr. Seuss sales are soaring just days after it was revealed that six of his books will not be published anymore.

News 12 reported earlier this week that six of the children's author's books will be pulled due to racist and insensitive imagery.

Now some of his classics, including "The Cat in the Hat," "Oh the Places You'll Go," and "Green Eggs and Ham," are all on Barnes & Noble's and Amazon's top-10 best sellers lists.

As for the books that will be discontinued, readers are probably not going to find them anymore. They are no longer available on the retailers' website or on the official Dr. Seuss website.
