Hundreds of San Francisco residents discovered this spring that photographs documenting their neighborhoods, businesses, and community events had vanished from city-administered digital archives — casualties of an automated deduplication process that flagged and deleted images deemed redundant across the San Francisco Public Library's digital collections and the Planning Department's property records system. The purge, which began in January 2026, has left gaps in records stretching back to the 1970s.

The timing is raw. San Francisco's Mission District, Chinatown, and Tenderloin neighborhoods have spent years building community-driven documentation projects specifically because they distrust that official institutions will preserve their stories. Finding those contributions gone — even partially — has reopened old wounds about who controls the city's memory.

What the Algorithm Removed

The San Francisco Public Library's San Francisco History Center on Larkin Street houses one of the most significant municipal photo archives on the West Coast. When the library migrated roughly 340,000 digitized images to a new content management platform in January, an automated deduplication tool identified near-identical files and retained only one version, discarding the rest. Staff say the tool flagged images with more than 85 percent visual similarity — a threshold that treated slightly different scans of the same print, or photographs taken seconds apart at the same event, as waste.

Community members who had donated scanned family photos to the library's Western Neighborhoods Project and to the nonprofit San Francisco Heritage say some of their contributions were among the deleted files. The Planning Department's online property viewer, which links historic exterior photographs to parcel records for addresses across the city, also shows broken image links for properties in the Excelsior and Outer Sunset districts.

Volunteer archivists with Chinatown Community Development Center on Haight Street have been among the most vocal. The organization spent considerable staff time digitizing photographs of Grant Avenue storefronts from the 1980s and 1990s and submitted copies to multiple city repositories specifically to guard against single-point loss. Finding duplicates treated as redundant rather than as archival redundancy — an accepted preservation standard — has frustrated advocates who argue the city confused digital housekeeping with conservation.

Residents Push for Transparency and Recovery

At a community meeting held June 28 at the Tenderloin Museum on Turk Street, more than 60 residents gathered to share accounts of missing images and demand answers from library administration. Several attendees described submitting records requests under the California Public Records Act to obtain documentation of which files were deleted and why, citing the January start date for the automated process as the outer boundary of their search window.

The San Francisco Public Library has not publicly confirmed the total number of images permanently lost versus those recoverable from backup servers. Digital preservation specialists generally recommend retaining at minimum two geographically separate copies of any archival file — a standard the library's migration plan did not appear to follow for all collections, according to documentation reviewed at the June 28 meeting.

Recovery efforts are underway on at least two fronts. The Internet Archive, headquartered on Funston Avenue in the Richmond District, crawled portions of the library's public-facing image database as recently as November 2025, meaning some deleted files may be recoverable through Wayback Machine snapshots. Separately, SF Heritage has asked donors who contributed digital files before 2025 to check personal hard drives and cloud backups for original uploads.

For residents who cannot recover their lost images, the practical advice from archivists at this point is consistent: file a written complaint with the City Librarian's office at the Main Library on Larkin Street, attach any metadata or filenames you retain, and submit a parallel request to the Planning Department's Records Division if your property photos are affected. Both offices are required under state law to respond within 10 business days. Community groups are also circulating a shared spreadsheet to catalog known losses — a crowdsourced audit the city has not yet attempted on its own.
