Barnes & Noble, the largest U.S. bookstore chain, is cutting jobs as revenue at its Nook tablet unit continues to shrink. "As we've aligned Nook's cost structure with business realities, staffing levels in certain areas of our organization have changed, leading to some job eliminations," Mary Ellen Keating, a spokeswoman for the New York-based retailer, said in an email. She declined to say how many jobs were cut and from what areas of the company. Barnes & Noble reduced Nook prices during the holidays amid continued competition from Apple's iPad.
