Marin history buffs, start your engines. Using just a few words, describe the subjects of the historical photos above, and pinpoint the year each photo was taken. To make it easier, here’s the answer for photo No. 1: Library founder Anne T. Kent, 1976. In the 1920s, Anne T. Kent, a Long Island librarian who married into Marin’s influential Kent family, was instrumental in establishing the Marin County Free Library system. In 1974, she initiated an oral history program at the library. Today, the Anne T. Kent California Room, located on the fourth floor of the Marin County Civic Center, is an archive of photos, maps, books and newspapers relating to Marin County’s colorful history.
