Under everything this site says lies one structured record. The prose is where the reading happens; the record is the spine it hangs on. It holds separate, numbered findings, and each one carries its own standing, the sources it rests on and the pages that use it. The count shows how much has been pinned down, not how much has been written. The figures below were taken on 10 September 2026. Later changes to the record will leave this text stale unless the figures are refreshed or generated when the site is built.

The findings come first: 385 separate claims about the corner and the people in it. They do not all carry the same weight, and the record keeps them apart. 317 are confirmed. 53 are carried only as probable and are hedged wherever they appear. 8 are open leads, not yet worth asserting. 6 are false trails, followed, ruled out and kept so that nobody chases them again. One is disputed. Nothing moves quietly from one column to the next.

Behind those findings stand 709 sources, among them newspapers, civil-register acts, address books, permits, deeds, photographs, advertisements, maps and web pages. Behind the sources stand 2,817 items of evidence: the scans and photographs themselves, the crops cut from them, and the transcriptions and readings made of each. The record names 75 people, 12 firms and 6 places, and it lists 35 musical acts that played at the venue.

The building's later life as a venue is counted too, with 192 performances and 13 related releases. Some of those releases contain only particular tracks attributed to the venue; others have no established recording-location credit. The rest of the structure is made of 20 recorded spans of occupancy, 45 links between people, firms and places, 44 dated turning points and 10 standalone studies. There are also 32 tracked questions, of which 13 are still open and 6 are being worked on.

Two habits keep the record honest. Any change to accepted knowledge goes through a reviewed proposal at the command line, and the readable tables and lists are rebuilt from the core records instead of being kept by hand as a second source of truth. A count is not a measure of completeness. Six places and twelve firms are all the corner has yielded, not a target met; the open questions are the record owning up to what it still does not know. The counts let a reader check the site against itself; they are not there to show size.

Most of what the record holds looks like the plainest thing in it. Below is a page of the Rotterdam address book, from its trade section for carpets and furnishings, with the corner's firm among the businesses listed: one document among the thousands the whole record is built from.
