Link to March 31 New York Times article, "As E-Books Gain Popularity, You Can't Even Judge a Cover".
Excerpt: Bindu Wiles was on a Q train in Brooklyn this month when she spotted a woman reading a book whose cover had an arresting black silhouette of a girl’s head set against a bright orange background.
Ms. Wiles noticed that the woman looked about her age, 45, and was carrying a yoga mat, so she figured that they were like-minded and leaned in to catch the title: “Little Bee,” a novel by Chris Cleave. Ms. Wiles, a graduate student in nonfiction writing at Sarah Lawrence College, tapped a note into her iPhone and bought the book later that week.
