A shop where books are bought and sold is a bookshop or bookstore. Books are also sold in some department stores, drugstores and newspaper vendors. Books can also be borrowed from libraries. Google has estimated that as of 2010, approximately 130,000,000 distinct titles had been published. In some wealthier nations, the sale of printed books has decreased because of the use of e-books, though sales of e-books declined in the first half of 2015.
