Shaping San Francisco is a participatory community history project documenting and archiving overlooked stories and memories of San Francisco. We do this in a variety of ways. We have a vast digital archive at http://foundsf.org where we invite everyone to contribute to our shared history. We hold Public Talks regularly at 518 Valencia, and co-host history programming with other organizations around the Bay Area. We conduct walking and bicycle history tours at least a half dozen times each season, and have two seasons of Talks and Tours each year. And we often partner with local university classes, helping students to produce new historical research that we incorporate into our online archive.
