The bookseller announced that its newly unveiled e-reader will feature the "biggest collection of Marvel comics on any tablet device", in addition to its extensive library of books and magazines.
The Nook Tablet will be Wi-Fi ready with a 7-inch VividView IPS colour touch panel and a 1.2GHz dual-core OMAP4 processor. It boasts a screen resolution of 1,024x600, and features 1GB of RAM, 16GB of storage and microSD expansion support.
Amazon's upcoming Kindle Fire is expected to bring the device fierce competition. Marvel's rival DC Comics previously sided with Amazon to bring its titles to the e-reader. Barnes & Noble responded to the announcement by pulling DC's books from its stores.
Barnes & Noble lifted the lid on the Nook Tablet during a New York press conference earlier today. It also announced price drops for the Nook Colour and Nook Simple Touch, which will now cost $200 (£124) and $100 (£62), respectively.
The Nook Tablet is released on November 18, priced at $249 (£155).
