The Scrolls, The Complete Book of Scrolls, and The Greatest salesman in the World were three different books. The specific differences were as follows: The Sheepskin Scrolls are a series of scrolls containing many teachings on personal growth, leadership, success, and wealth. The Book of the Goatskin Scrolls contained all the scrolls in the book and gave a comprehensive summary and explanation. The World's Greatest salesman is a book about success and sales. It mainly tells how a salesman named Joshua became one of the world's greatest salesmen through practice and skill. This book mainly focuses on marketing techniques and successful strategies rather than specific business practices. The Scrolls and The Book of Scrolls focused on personal growth and success, while The World's Greatest salesman focused more on business practice and sales techniques. Although they were both books about success, their focus and style were different.
