Enid Blyton
Enid Blyton is in The Guinness Book of Records as one of the world's biggest selling writers. She is also included because she wrote more books than almost any other writer (about 700). Her books were published in many different languages. She said that she found writing them easy. Her books still sell in large numbers, and used to be owned by her family. A few years ago her family sold them, and now her works belong to a private company.
