How the record is filed
Every dossier carries three index fields beyond its geography — what became of the place, whether the door opens, and how the paper holds up. These are those shelves:21 indexes over 3,516 dossiers. Claims are reported, not endorsed.
By status — what became of the place
Operating, abandoned, demolished or simply unresolved — the field records what the sources say about the ground today.
By access — whether the door opens
A filing, not an invitation. Restricted and private files stay documented — admired from the legal distance.
By evidence — how the paper holds up
The ladder, from verified history to the honest bottom rung. The grade describes the documentation, never the ghost.
The other shelves
The same dossiers, filed differently — by kind of place, by what witnesses claim, by geography and by the decade the walls went up.
