Coverage by reign

Which reigns of each roll series are OCR'd here from public-domain Internet Archive scans, beside the number of printed volumes that exist — a finding aid for what's covered and what still needs locating. Printed-volume counts are approximate (from the published HMSO run) and being verified.

green = as many volumes as the printed run; amber = partial. Counts are the OCR'd (public-domain) volumes. “Scanned, awaiting OCR” volumes are queued; “no scan found yet” volumes are being hunted across the Internet Archive — several turn out to hide under wrong catalogue metadata, identified from their title pages.
