This Catalogue of British Town Maps locates town maps extant in UK public archives and libraries. It provides details of almost 8,000 maps and provides for each the key cartographical and other features and the location of publicly-accessible exemplars. Associated with each catalogue entry is a PDF image outlining the area covered by the map.  Catalogue information is available from a straightforward and easily searchable user interface. For ease of access the maps are also searchable via a simple Google maps search function.
