Barnes & Nobles (BKS) is getting in on the book-book-booking game, but it is far from alone in the effort.
On Tuesday, Microsoft (MSFT) announced its own plan to launch a digital book distribution platform for its Xbox gaming console.
Barnes & Novell (BNN) has teamed up with Amazon (AMZN) to bring its e-book offering to the Kindle.
The e-books market is projected to reach $1.5 trillion by 2021, up from $1 trillion last year, according to eMarketer.
It is expected to be worth about $200 billion in 2021.
