As part of an ongoing campaign, Windstone Editions, a company located in North Hollywood, California, supports independent bookstores with an unusual profit-sharing program: It donates 10 percent of the company's profits from the sale of its line of cast stone bookends to independent booksellers associations. Windstone is the exclusive vendor of bookends, figurines, candleholders, sconces, and other sculptural items designed by artist M. Peña.
