1:10 000 The most recent revision of the component 1:10 000 scale National Grid maps of 1:50 000 Series sheet 265 Bath are listed below, along with the surveyors’ names and dates of survey. The surveyors were A J M Barron, R A Edwards, R A Ellison, A R Farrant, K R Royse, T H Sheppard, P J Strange and R K Westhead. Amendments to some maps were made by R J Wyatt in 1977–1985. Maps which have not been resurveyed since the 1965 publication of Sheet 265 at 1:63 360 are marked with an x. These maps, together with those listed as being surveyed only in part, have been reconstituted at the 1:10 000 scale from older component maps at the scale of 1:10 560 scale of either the National Grid or County Map series. Copies of maps from these and earlier large-scale surveys are available for reference in the BGS Libraries at Keyworth and Edinburgh, and at the BGS London Information Office in the Natural History Museum, South Kensington. Copies for purchase are produced on a print-on-demand basis and are available from the BGS Sales Desk.
Digital geological map data
In addition to the printed publications, many BGS geological maps are available in digital form. Details are given on the BGS website. National coverage of digital geological map data (DiGMapGB) is derived from geological maps at scales of 1:625 000, 1:250 000 and 1:50 000. Selected areas also have digital geological data derived from 1:10 000 scale geological maps. Digital geological data for offshore areas is derived from 1:250 000 scale geological maps.

Books and reports
Books and technical reports relevant to the district, including biostratigraphical reports, are listed in the References. Reports may be consulted at the BGS library or purchased from the BGS Sales Desk.
Documentary records collections
Detailed geological survey information, including large scale geological field maps, is archived at the BGS. Enquiries concerning unpublished geological data for the district should be addressed to the Manager, National Geoscience Data Centre (NGDC), BGS Keyworth.
Borehole and trial pit records
Borehole records for the district are catalogued in the NGDC at BGS Keyworth. Index information, which includes site references, names and depths for these boreholes, is available through the BGS website. Copies of records in the public domain can be ordered through the same website, or can be consulted at BGS Keyworth.
Records of water wells, springs, and aquifer properties held at BGS Wallingford can be consulted through the BGS Hydrogeology Enquiry Service.
These data are held digitally in the National Gravity Databank and the National Aero-magnetic Databank at BGS Keyworth. Seismic reflection data from coal and hydrocarbon exploration programmes is available for the north of the district. Indexes can be consulted on the BGS website.
BGS Lexicon of named rock units
Definitions of the stratigraphical units shown on BGS maps, including those named on Sheet 265 (Bath), are held in the BGS Stratigraphical Lexicon database, which can be consulted on the BGS website. Further information on this database can be obtained from the Lexicon Manager at BGS Keyworth.
The photographs used in this Sheet Explanation are part of the National Archive of Geological Photographs, held at BGS in Keyworth and Edinburgh. Part of the collection can be viewed at BGS libraries at Keyworth and Edinburgh, and on the BGS website. Copies of the photographs can be purchased from the BGS.
Information on the collections of rock samples, thin sections, borehole samples (including core) and fossil material can be obtained from the Chief Curator, BGS Keyworth. Indexes can be consulted on the BGS website.
