The newly-updated Other San Francisco Locales archive has been a catch-all for the neighborhoods that do not have enough image files to get their own archive. Or perhaps these neighborhoods are distinct and spread outside the other archives that have developed over the years. Fort Mason, the Marina, Chinatown, North Beach - all are included in the Other archive.
Over the years, some images end up getting moved, like they did during this update. Golden Gate Park and Ocean Beach eventually moved to the Sunset and Richmond Districts archive, because it makes sense geographically. Many images moved to the Western Addition archive after the logical path that that archive should encompass USF, Lone Mountain, NoPa, etc.
The Other archive also includes photos from San Francisco that may not have a specific location attached. Where exactly was that String Cheese Incident road case stencil photo taken? The 1997 David Solnit poster was photographed somewhere in SF, and ended up in the Other section.
As the Stencil Archive project continues to develop, some new main archives may get pulled out of the Other section. After writing this post, it may be time soon for North Beach, Chinatown, and Fishermans Wharf to get a new archive. We'll put this down on the future to-do list.
