While many authors fade into obscurity, a select few who write for children leave an indelible mark. Legends like Dr. Seuss, Beatrix Potter, and E.B. White have brought joy to families for decades with their enduring classics. No bookshelf is complete without the antics of a hat-wearing cat, a kind-hearted spider, or a mischievous rabbit named Peter.
Though Seuss, White, and Potter have long dominated best-seller lists, the 1990s brought a seismic shift. J.K. Rowling, a struggling British author, cast a spell that transformed children's literature. Her debut, "Harry Potter and the Sorcerer's Stone," introduced a young wizard who captivated the world. With seven books, Rowling soared to become one of history's most successful authors, embedding terms like Hogwarts, Muggle, and Quidditch into our everyday language.
Rowling's triumph reshaped the landscape of children's best-sellers. Publishers Weekly last compiled the list in 2001, long before the 2007 release of "Harry Potter and the Deathly Hallows," which sold 15 million copies in its first day. This staggering feat surpassed the lifetime sales of the long-standing champion, "The Poky Little Puppy," first published in 1942 [sources: Forbes; Random House].
By 2011, J.K. Rowling had sold approximately 450 million Harry Potter books [source: ABC News]. The term "approximately" is used because tracking exact sales figures is as challenging as catching a Golden Snitch in a Quidditch match. In fact, by the time you finish this sentence, hundreds more copies of Harry Potter and Cat in the Hat have likely been purchased.
Proceed to the next page to explore the 20 best-selling children's books of all time, including the staggering sales figures for, dare we say it, Harry Potter. You might even spot a personal favorite or two among them.
