With no shortage of eco-friendly titles, booksellers are expanding their Environmental Sections, creating entirely new "green" sections, and offering tie-in events and sidelines to meet increasing customer interest. Vroman's Bookstore in Pasadena, California, has featured a permanent section called Living Green, a mix of books and sidelines, since the fall of 2007, and Changing Hands in Tempe, Arizona, is emphasizing a "Go Green" theme via events throughout January and the rest of 2008.
