In the year 2000 the BGS internal report series were reorganized into three series. Research reports (RR) for reports of significant scientific content but which were not formally published with print runs.; Commisioned Reports (CR), reports that were commissioned by customers and are mostly restricted access and OR reports - Open Reports, reports that are a record of work undertaken in BGS and are made available to the public as downloads through NORA. This series is the Open Reports.
