Public access to the International Library in Ordnance Survey head office ceased in March 2003.ĭuring 20, Ordnance Survey and TNA sought suitable custodians of all parts of the collection and relocated them. Working with OS staff and advised by specialists, the material was appraised, and determined what would be kept, and where. Responsibility for these public records then passed to The National Archives (TNA). In 2002, Ordnance Survey deemed its International Library no longer needed for operational purposes. OSD’s title was changed to OS International and its priorities turned to consultancy, mainly in Eastern Europe, while traditional map production gradually declined. It was named Technical Information and Support Services and kept that title for seven years, before being renamed International Library in 1991.īy 1991 the last significant, aid-funded mapping projects had been completed by OSD and all survey parties had been disbanded. When the two organisations were merged in 1984, all international aerial photographs, maps, and survey data were amalgamated into one working collection. Ordnance Survey already had its own international division. Then, in 1984, the organisation was merged with Ordnance Survey and given a new title: Overseas Surveys Directorate, OS (OSD). Some non-Commonwealth countries such as Ethiopia, Liberia, Sudan, and Yemen Arab Republic were mapped by DOS between 19.ĭuring the 1970s, government reviewed the DOS’ purpose. In 1957, DCS was renamed the Directorate of Overseas Surveys (DOS) to reflect the independence of many former Colonies. In 1946, the Colonial Office established the Directorate of Colonial Surveys (DCS), to be a central survey and mapping organisation for British colonies and protectorates. The history of the International Collection The International Collection was the result of the work of the Directorate of Colonial Surveys, the Directorate of Overseas Surveys, Ordnance Survey (Overseas Surveys Directorate) and Ordnance Survey International.

The following stockists are also able to supply historical mapping: NameĪrchives of map, photography and survey records of countries around the world If these sources don't hold the information you're looking for you may find the Vision of Britain and British History Online websites of interest. If you're looking for old maps of Great Britain you can contact or visit one of the following libraries.
The original historical maps now reside with local libraries around the country. We also sell various historical products produced by our licensed Partners. We sell a limited reproduction range of one inch to one mile maps (revised from the late 1800s and published in the early years of the 1900s) from our OS map shop. Small-scale mapping is then produced as a reflection of our large-scale mapping database, sourced at the time of the last cartographic revision. We define historical mapping as mapping that no longer reflects the situation on the ground. Our detailed mapping reflects features on the ground at the time of last survey.
