Locke's "Some Thoughts Concerning Education" was a runaway best-seller. During the eighteenth century alone, "Some Thoughts" was published in at least 53 editions: 25 English, 16 French, six Italian, three German, two Dutch, and one Swedish. It was also excerpted in novels such as Samuel Richardson's "Pamela" (1740–1), and it formed the theoretical basis of much children's literature, particularly that of the first successful children's publisher, John Newbery. According to James A. Secord, an eighteenth-century scholar, Newbery included Locke's educational advice to legitimise the new genre of children's literature. Locke's imprimatur would ensure the genre's success.
