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 PC in Maps. 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 Enquiry Desk. Our Main Catalogue can be searched for titles, or the Maps listing of electronic resources browsed. Subscription web resources and locally-networked resources may be limited to the Maps Reading Room owing to licensing restrictions.

However, some subscription web 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 listing 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 enquiry desk for details.
