| http://www.w3.org/ns/prov#value | - Amazon sold more e-books than physical books during the last three months of 2010, the online retail giant has claimed.Amazon announced in July 2010 that it was selling more e-books than hardbacks, but he is no cause for amazement because hardback sales have been declining for years and are a small percentage of books sold in any case.Outselling paperbacks, on the other hand, is a big deal.
