What a city remembers depends on who gets to keep the record.
Libraries, local archives and small publishing projects make memory less dependent on the platforms that happen to be popular this year.
Who keeps the record?
The memory of a neighbourhood does not live in one archive. It is spread across notices, photographs, recordings and the people who know why a room mattered before its name changed.
Small libraries and community publishers do more than preserve material. They make it possible to find, question and add to a record without asking a platform's permission.
