Lawrence Ferlinghetti’s hand-painted sign, taped to the window of his office at City Lights, overlooking Columbus Avenue, reads: “OPEN DOOR.” That all-inclusive ethos, which has guided the San Francisco bookstore since Ferlinghetti co-founded it in 1953, will be fully evident when the shop hosts an open house on March 24 to celebrate Ferlinghetti’s 100th birthday.

The bookstore, at 261 Columbus Ave., will welcome the public from 1 to 5 p.m. on that Sunday to honor the life of the world-renowned poet and publisher. Three neighboring spots in North Beach — Canessa Gallery, Café Zoetrope and Vesuvio’s — will also take part in the festivities.
