As the second step in a major rebrand programme, HarperCollins is relaunching 10 more hilarious Dr. Seuss books, including such all-time favourites as How the Grinch Stole Christmas!, Mr. Brown Can Moo! Can You? and Dr. Seuss' Sleep Book. In response to consumer demand, the bright new cover designs incorporate much needed guidance on reading levels, with standard paperbacks divided into three reading strands - Blue Back Books for parents to share with young children, Green Back Books for budding readers to tackle on their own, and Yellow Back Books for older, more fluent readers to enjoy. How the Grinch Stole Christmas! belongs to the Yellow Back Book range. It has also been adapted for the big screen, and is now a blockbuster movie starring the irrepressible Jim Carrey.
