NEW YORK (AP) — Barnes & Noble is rolling out two new versions of its Nook tablet with sleek new hardware and a sharper high-definition screen. The bookseller’s move heightens the already intense tablet wars heading into the holiday season.

Barnes & Noble said Wednesday that its new Nook HD will come in two sizes, one with a 7-inch screen (measured diagonally), starting at $199, and one with a new 9-inch diagonal screen, called the Nook HD+, starting at $269.

In addition to the new HD screen and a lighter body, Barnes & Noble is also increasing the services the Nook offers, adding a video purchase and rental service, allowing users to maintain different “profiles” and making it easier to browse titles in its book and magazine stores.
