Life.com, 7-12

Life.com includes the entire archives of photo giants Life magazine and Getty Images. Users can view galleries curated by the site's editors or search the library by names, dates, subjects, and locations. The archive chronicles current events, too, with daily news galleries and the addition of 3,000 new Getty photos a day. Life's last editor, Bill Shapiro, who heads up the new project, wants students, teachers, and parents to use the site to make history more tangible. "We didn't want simply to create a historical repository or a dusty archive. We wanted these events to feel as alive as they did when they happened."

Photos on the site are organized into five channels: news, celebrity, travel, animals, and sports. Visitors can print individual images and share them through sites like Facebook, Twitter, and Del.ic.ious. New features of Life.com, due to roll out in the coming months, will allow users to create their own photo galleries (on, say, the life and work of Maya Angelou, for English class, or animal life in the Everglades, for science). All the site's tools will be free.
