As an art history major at Yale University, Vera Zlatarski would roam the dimly lit hallways at 3 a.m., studying images that her professors had tacked up because, even though they would be on the exam the next day, they weren't in textbooks. "We didn't have cellphones, much less resources such as ARTstor to help," explains Zlatarski, referring to the organization where she was just appointed general counsel and secretary.

The nonprofit, which was started in 2002, has a digital library of more than 1.6 million images in the arts, architecture, humanities, and sciences. With collections from the Metropolitan Museum of Art, Museum of Modern Art, Magnum Photos, and the Scala Archives, ARTstor aims to enhance teaching, scholarship, and research for its 1,400 educational institution subscribers.
