Restrictions on Re-use
Several of these Ordnance Survey series have been digitised for the Library by a third party. Use of these digitised maps for commercial purposes is currently restricted by contract. These restrictions cover the re-use of copies and extracts, as well as commercial use directly through our websites (Further information).
