A grand lightwell illuminates San Francisco's favorite subjects: graphic novels in the Teen Center, poetry in the Robert Frost Collection, civil rights in the Hormel Gay & Lesbian Center, and comic relief in the Schmulowitz Wit and Humor Collection. Check out the 2nd-floor wallpaper made from the old card catalog – artists Ann Chamberlain and Ann Hamilton invited 200 San Franciscans to add multilingual commentary to 50,000 cards. The library quietly hosts high-profile basement lectures, plus enlightening Skylight Gallery ephemera exhibits.
