Barnes & Noble Inc introduced a new Wi-Fi version of its "Nook" electronic book reader on Monday and lowered the price on its 3G-compatible Nook amid intensifying competition in the fast growing electronic-books industry.
Barnes & Noble, the No. 1 U.S. specialty bookseller by sales, priced the Wi-Fi version of Nook at $149 and reduced the price on its 3G-compatible Nook to $199.
The Nook also competes with Amazon.com Inc's Kindle. Barnes & Noble launched the Nook in October.
Barnes & Noble is set to report its fourth-quarter earnings next Monday.
