The Law of Success is a book written by Napoleon Hill in 1925. It was originally released as a set of 15 separate booklets before being consolidated into a single-tome book. There were 118 limited edition copies, which were given to many of America's most successful individuals, all of whom had contributed to the content of the book. Orne Publishing used one of these original copies to create a reprinted version of The Law of Success in 2010. The Law of Success in 16 Lessons is an edited version of Napoleon Hill’s first manuscript, which was reworked under the advisement of several contributors. This version was initially published in 1928 as a multi-volume correspondence course. Later editions consolidated the material into a single hardcover book. Source: Wikipedia (en)
