With his unique combination of hilarious stories, zany pictures and riotous rhymes, Dr. Seuss has been delighting young children and helping them learn to read for over fifty years.

As part of a major rebrand programme, HarperCollins has relaunched 17 of Dr. Seuss's best-selling books, including such perennial favourites as The Cat in the Hat, Green Eggs and Ham and Fox in Socks. In response to consumer demand, the bright new cover designs incorporate much needed guidance on reading levels, with the 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. Hop on Pop belongs to the Blue Back Book range.

Theodor Seuss Geisel – better known to his millions of fans as Dr. Seuss – was born the son of a park superintendent in Springfield, Massachusetts, in 1904. After studying at Dartmouth College, New Hampshire and later at Oxford University in England, he became a magazine humorist and cartoonist and an advertising man. He soon turned his many talents to writing children’s books and his first book – ‘And to Think That I Saw It on Mulberry Street’ – was published in 1937. His greatest claim to fame was the one and only ‘The Cat in the Hat’, published in 1957, the first of a successful range of early learning books known as Beginner Books.
