NEW YORK (AP) — IN THE RED: Barnes & Noble lost $45.2 million during its first quarter. Weak sales of its Nook e-readers and an unchanged full-year outlook left investors unimpressed. They sent its shares downward.

SHADES OF GRAY: If there was a silver lining, it was found in "Fifty Shades of Grey." Booming sales of the erotic novels, which occupy the top three spots on The New York Times' list, helped to at least narrow the booksellers losses from the same quarter last year.

BLANK SCREENS: The Nook unit — which includes e-readers, digital content and accessories — reported revenue that was essentially flat. Revenue from devices dropped partly because of lower prices. Chief Financial Officer Michael Huseby said Nook prices were about 23 percent lower than a year ago.
