National Library of Scotland
The National Library of Scotland map collection is one of the ten largest in the world, covering all parts of the globe, through some 700 years, from medieval manuscript maps to current digital mapping.
We hold a comprehensive collection of Ordnance Survey mapping from the 1840s to the present day, and a comprehensive set of 20th century mapping for England and Wales.
We make over 80,000 Ordnance Survey and other maps freely available on our website at: http://maps.nls.uk
Our main solution is providing copies, in hard copy and digital forms, of in-copyright Ordnance Survey maps.
The full service is described at: http://www.nls.uk/collections/maps/services/reprographics/os-licence
