By its own description, the LESBIAN HERSTORY ARCHIVES is "the kind of place that inspires fantasy." The oldest and largest lesbian archive in the world, the limestone townhouse in Park Slope boasts tens of thousands of volumes, from a slew of 1950s paperbacks with intriguing titles like The Women's Barracks to gay women's periodicals such as Does Your Mama Know? and The Empty Closet. Hundreds of buttons and T-shirts, including a prized Lavender Menace shirt from the 1970s, reveal the story of protest rallies and marches through the decades. Anyone is welcome—gay, straight, with or without dangling appendages—but visits must be scheduled by appointment.
