HALLATROW, UNITED KINGDOM - DECEMBER 12: Bookbarn International employee Ken Buckland looks for a second hand book that has been ordered over the Internet in their warehouse on December 12, 2008 near Hallatrow in Somerset, England. Selling most of their books online via websites such as Amazon.com, Bookbarn International is the UK's largest second hand book warehouse with over 5 million titles stored in two giant barns in a field in Somerset. Helped in part by the credit crunch, sales of second hand books have risen sharply recently with the weak British pound only helping the Bookbarn to sell more books internationally.
