Walker Books, Inc., is the fastest-growing book distributor in the United States. Established in 1981 in Palo Alto, California, Walker Books was originally a side project of founder and current president Curtis Walker, who at the time was employed by a local law firm. Because reading was much more than just a hobby of his, he decided to use some of his savings to buy an abandoned restaurant and convert it into a neighborhood bookstore, mainly selling used books that were donated and obtained from flea markets. When the doors first opened, Walkor’s wife, Lauren, was the only employee during the week and Curtis worked weekends. At the end of the first fiscal yaw, Walker Books had grossed $20,000 in sales.
