According to an article by David Streitfeld in the July 5, 2013 issue of The New York Times, Amazon.com now sells
"about one in four new books, and the vast number of independent sellers on its site increases its market share even more. It owns as a separate entity the largest secondhand book network, Abebooks. And of course it has a majority of the e-book market."
The main issue raised in Steitfeld's article, entitled "The Price of Amazon," was Amazon's ability to control the prices of new books and ebooks.
