Barnes & Noble has announced that it does not intend to carry books published by Amazon in any of its 703 retail locations. It's a move sure to deepen the wedge between the two companies, and B&N cites Amazon's continued taste for exclusivity as the primary reason for the decision. In a statement to The New York Times, chief merchandising officer Jaime Carey doesn't mince words, claiming Amazon's practices have "undermined the industry as a whole" and "prevented millions of customers from having access to content." While consumers will have access to the works on BN.com, selection there will also be limited — B&N said back in August that it would not sell physical copies of books from Amazon Publishing unless it could also make an e-book version available to its Nook customers. When you consider the rapid growth of that business, it makes sense that B&N would use its massive retail presence as a counterweight to Amazon's knack for snatching up exclusives.
