Historical maps are valuable resources for research in areas such as toponymy (the study of place names), sociology, geography and history.

The maps have been scanned and produced in PDF format. The Maps, Official Publications and Statistics Unit are able to reproduce high-quality large-scale prints of these maps (details of this service is available here) if required.

Many of these maps are also available in paper on Level 7 of the library. Please ask staff at the Enquiry Desk on Level 7 for further information on accessing maps either online or paper format.
