For historical societies

A lot of local history lives with small volunteer groups, on websites that are one lapsed domain away from going dark. History Underfoot is starting a coalition of Atlanta-area historical societies and history groups to share the technical work: rebuilt websites (free); rescue copies of what you have now, in open formats; and pages that search engines and AI assistants can find and credit. Every group keeps its own material. How it works
