Genealogia w Archiwach

A Polish state-archives portal of scanned metrical books — civil registration from the Prussian partition (1874 on), duplicates of Roman Catholic parish registers from before that, and population and registration books from 1837. Separate from Szukaj w Archiwach and run by its own archives. Secondary sources say the scans are free and need no account; NOBODY HERE HAS CONFIRMED THAT, because the site is a Vaadin application that renders nothing without JavaScript, so it is marked unsurveyed rather than taking a blog's word for what it costs. SCANS ARE SERVED BY A LORIS IIIF IMAGE SERVER and can be read in place without downloading: /loris/<id>/<x,y,w,h>/<width>,/0/default.jpg returns an arbitrary region at up to TWICE native resolution, which is enough to settle a difficult hand. info.json returns 403 while image requests succeed, and anything above 2x returns a bare 404. The viewer's own canvas is tainted, so the tile server is the route and screenshots are not. THE PORTAL WILL NOT OPEN A UNIT BY ITS SIGNATURE: a scan's modal id resolves only inside the current search result set, so a neighbouring scan cannot be reached by guessing an id. The route that works is to open any scan's modal, click 'View the document' to expose the unit's own scan list, click Show on the scan wanted, and take the new Loris id from the network log.
