Bookstore chain Barnes and Noble Inc (NYSE:BKS) has protested Amazon’s (NASDAQ:AMZN) exclusive agreements with publishers, agents and authors by refusing to sell books published by Amazon at its 703 book showrooms across the country. The books will, however, be available for sale on its website.

According to Barnes & Noble, Amazon’s relentless push to reach ‘exclusivity’ agreements with publishers, agents and authors has undermined the industry as a whole. Amazon recently signed up self-help author Tim Ferris and purchased over 450 children’s books by Marshall Cavendish. Amazon also entered in to a deal with Houghton Mifflin Harcourt to sell print versions of its books.

Barnes and Noble’s move will intensify rivalry between the two companies, already locked in competitive battle with their respective tablet products. Barnes and Noble is taking a big risk as its Nook e-reader is already not making a huge dent in the new tablet market.

Here’s how these two stocks are reacting to the news:
