forwarded by Angie -------- Original Message -------- Subject: New OS County Map records available for England and Wales (1841-1952) Date: Mon, 9 Sep 2013 10:07:48 +0000 From: Fleet, Christopher <[log in to unmask]> Reply-To: A forum for issues related to map & spatial data librarianship <[log in to unmask]> To: [log in to unmask] 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.
