HALLATROW, UNITED KINGDOM – DECEMBER 12: Second hand books are stacked on shelves at the Bookbarn International in one of their warehouses on December 12, 2008 near Hallatrow in Somerset, England. Currently selling up to several thousand books a day and mostly online via Web sites 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.
