Sometimes known as the "One-Inch Collection", this is an archival collection of rock samples collected by BGS field staff during surveys within England and Wales, arranged by 1-inch (or 50 K) scale BGS geological map sheet area. It was intended as a representative suite of the lithologies present in each sheet, although this was only partially achieved. Documentation is via archive of rock sample collection sheets (see COLLECTIONSHEETS) but is poorly coordinated at present.

Registers of macrofossils in 127 volumes, covers the whole of the UK. Within each volume, data is arranged sequentially usually by collectors no. The data set began with the first Palaeontologist in the Geological Survey of Great Britain.

Annotated Scottish 1 inch scale maps. Printed topography with hand annotated fossil locations and geology with hand drawn cross sections, colour-wash with index and observations. Considered working material towards published geological maps.
