We collect and maintain geospatial data, cartographic applications, digital aerial photography and scanned-in historic map materials.

About the collection

We receive digital mapping data from a variety of sources. Access and management varies according to the data format, location, and licensing arrangements.

What is available online?

What is available in our Reading Rooms?

The Maps Reading Room is the best place to view digital map resources, as many materials require use of specialised software or are limited in their network access. Some map data are only stored, or accessible, on standalone PCs in the Maps Reading Room. All CDs with a 'Maps e-media...' shelfmark are stored in the Maps Reading Room, to be loaded and used on the dedicated PC next to the Reference Enquiry Desk. 

You can search for titles in Explore the British Library, our main catalogue, or browse the list of Maps electronic resources. Some web resources and locally-networked resources are limited to the Maps Reading Room owing to licensing restrictions. Other subscribed resources with cartographic content are available in all Reading Rooms. This is true of online research indices and journals, as well as databases including scanned maps. Please refer to the list of Maps electronic resources for an indication of format and access.

Printing

Owing to varying copyright and licensing arrangements, printing is allowed for some, but not all, electronic resources, and is generally limited to non-commercial purposes. Ask staff at the Reference Enquiry desk for details.
