An important paper archive of a wide variety of miscellaneous geological information organised on the basis of its location within 1:50 000 scale geological map sheet areas in Great Britain. The majority of the data has been produced or collected by BGS staff since 1835 as part of the mapping programme. The data may not fit into any of the main collections, but is valuable for future projects and answering enquiries.

An important paper archive of a wide variety of miscellaneous geological information organised on the basis of its location within 1:10 000 scale geological map sheet areas in Great Britain. The majority of the data has been produced or collected from a wide variety of sources by BGS staff since 1835. Mainly acquired as part of the mapping programme new information is added on a regular basis. The data may not fit into any of the main collections, but is valuable for future projects and answering enquiries.

The dataset comprises plans of various types relating to mining activity, including abandonment plans, gathered since the 1800s. Most were collected as part of the BGS mapping programme and the type and amount of data available will vary considerably. The coverage for Northern England and Scotland is more comprehensive than for the rest of the country. The plans include working copies, compilations and interpretations which may be copyright or confidential. The general nature of some of the plans means that they may not be applicable to a specific site. Current holdings over 60,000.
