This series contains maps, plans, and atlases accumulated by the Foreign Office from library material, extracts from despatches and reports, and items collected by diplomats in the course of their work.
They are not specifically diplomatic maps, but contain historical information. Some are manuscript, original and unique maps. Others are printed, by one form or another: for example, engraved, lithographed, photozincographed, and so on. Some have manuscript additions. The maps are single sheets or gatherings of sheets (either flat or rolls) and published atlases.
