Kepler's Books and Magazines is an independent bookstore in Menlo Park, California. It was founded on May 14, 1955 by Roy Kepler, who had previously been a staff member of the Berkeley listener-supported radio station KPFA. It "soon blossomed into a cultural epicenter and attracted loyal customers from the students and faculty of Stanford University and from other members of the surrounding communities who were interested in serious books and ideas."
