In Saratoga, volunteers with the Friends of the Saratoga Libraries have run this shop out of the original Saratoga Library building, at the corner of Oak Street and Los Gatos-Saratoga Road, since 1983, restocking it from a donation drop the group installed beside the library's outdoor book return. The group's own page listed a paperback sale for Saturday and Sunday, October 17 and 18, 2026, in the Saratoga Library Community Room at 13650 Saratoga Avenue, with books at 50 cents apiece and a $5 bag deal on Sunday, credit cards accepted above a $5 minimum. A rotating local-artist display shares the walls with the shelves, the group's latest addition to the space by its own news block.

110 E Main St, Los Gatos, CA 95030
In Los Gatos, the Friends of Los Gatos Library trade gently used fiction and nonfiction up the stairs from the fountain on Civic Center Plaza, Tuesday through Sunday, closed only on Mondays, with a Free Little Library out front stocked in a different language each month. Members get a spin on a prize wheel the first Tuesday of every month, and a one-day Patio Book Sale was listed for Saturday, September 12, 2026, with everything at two books for a dollar out on the plaza. The regular shelves stay separate from that outdoor sale, so a quiet weekday afternoon is still the better bet for a slow browse.
