Index to the BGS collection of geologist's field notebooks and section books.

An index to the manuscript notebook collection was set up in the 1990's. The notebooks themselves contain detailed information gathered by BGS geologists (or other recognised geologists) from various sources as part of the mapping of Great Britain since the 1840s. Examples include observations linked directly to field slips, borehole logs, sections and drawings. All the notebooks held by National Geological Records Centre (NGRC) are indexed but other notebooks held in the Library may not be included. The index is to the notebooks and is not a detailed index of the information in the notebook. Detailed information from coalfield areas is held in the Happs Hall Index. For the basic field mapping work notebooks have now been replaced by field record sheets.该手稿笔记馆藏的索引体系于20世纪90年代建立。这些笔记收录了自19世纪40年代以来，英国地质调查局（British Geological Survey，BGS）地质学家（或其他公认地质学家）从各类渠道收集的详细资料，作为英国本土地质填图工作的组成部分，其内容示例包括与野外工作单、钻孔日志、地质剖面及绘图直接相关的观测记录。国家地质资料中心（National Geological Records Centre，NGRC）馆藏的全部笔记均已完成索引编制，但图书馆馆藏的其他笔记可能未被纳入该索引。该索引仅针对笔记本体，而非笔记内部的详细信息。煤田区域的详细资料收录于哈普斯霍尔索引（Happs Hall Index）中。目前，基础野外填图工作所用的纸质笔记已被野外记录表单取代。
