Record copies of published Admiralty charts, produced since 1800, are an important part of the archive. However, we do not have a copy of every chart ever published by the Hydrographic Office, but we do have the most complete collection in the United Kingdom. We do not have a copy of every correction to every chart, but it is possible to follow the history of most charts from the 1830s to the present day.
