The GSI is a recognised repository of the National Archives and has a statutory responsibility for the records of the organisation as a part of government. In practice, there are specific collections of more historical or important records that are separated in an Archive Room, that is protected from fire and environmentally controlled to enhance the long term preservation of those records. Although the majority of these are catalogued, current work in the IGH Programme with the Cartography Unit, aims to complete the cataloguing of all such records and to try and make information about them more accessible for users. Enquiries about the Archives are welcome and should be directed to Sarah Gatley at or 01 678 2837, but we are unable to undertake research. A personal visit may be required to view material and requires an appointment. More information about the Archives.
