For all clickable-graphic index fans, and OS county map searchers... we
have just completed a project over the last year to list all of our
holdings of Ordnance Survey six-inch and 25 inch to the mile County
Series maps of England and Wales - 152,332 records in total - and were
keen to publicise in the hope others may find this useful.
We have linked the County Series records to sheet boundary extents to
create clickable graphic indexes to all the sheets, and included the
results with our County Series and National Grid sheet records for
Scotland, which were listed some years ago.
Our new, renamed 'OS sheet records viewer' (
http://maps.nls.uk/geo/records/ ) replaces our former OS National Grid
viewer, and provides a single interface for viewing all these sheet map
records. It provides clickable indexes for OS County Series maps at
1:2,500 and 1:10,560 that were published for anywhere in the United
Kingdom from 1841-1952. This includes all the editions of map sheets at
these scales held by NLS, but also indicates which sheets we know were
published that NLS does not hold - especially early 25 inch editions. So
we hope the viewer provides a geographic portal for discovering when
large-scale OS maps were surveyed, revised and published for any
particular area - and which were published as combined sheets, insets,
extended and outsize sheets, etc. The viewer also includes sheetlines of
National Grid maps at 1:10,000 and larger scales for England and Wales,
but currently only specific dates of these National Grid maps for Scotland.
We realise that this metadata is fairly basic - essentially recording
sheet references, survey/revision and publication dates, and not looking
at further marginalia such printing states, reprint codes, etc., etc. We
realise it falls far short of typical carto-bibliographies by Roger
Hellyer... but we hope that this listing is still of some value at a
basic level for those interested in discovering sheets and dates of
published OS large-scale mapping.
We are very grateful to EDINA for funding the collection of this OS
County map metadata.
