Accessing Maps

Historic OSI Maps online
The National Library participated in a major digitisation project by the Ordnance Survey of Ireland. The OSI website offers online access to maps produced by the Ordnance Survey between 1829 and 1913 and also includes genealogical (location of schools, graveyards, churches, workhouses etc.) and environmental data. Readers can view these maps together with this additional data on the OSI website which is available to readers in the National Library's Online Services Room. 

Modern Ordnance Survey Maps 
Maps and Atlases published in book and spiral bound format are catalogued and stored with the Irish book collection and can be consulted in the Main Reading Room.
