Limnology global inland waters as part of the Earth System created a sub-discipline called global limnology. This approach considers the role of inland aquatic ecosystems in carbon cycling. Limnology is closely related to aquatic ecology and hydrobiology, which study aquatic organisms and their interactions with the abiotic (non-living) environment. While limnology has substantial overlap with freshwater-focused disciplines (e.g., freshwater biology), it also includes the study of inland salt lakes. The term limnology was coined by François-Alphonse Forel (1841–1912) who established the field with his studies of Lake Geneva. Interest in the discipline rapidly expanded, and in 1922 August Thienemann (a German
Faceted Application of Subject Terminology were impressed by its "ease of use, simple syntax, [and] suitability for use by non-specialist staff." However, several libraries in the same study were discouraged by a lack of communication with OCLC. Faceted Application of Subject Terminology Faceted Application of Subject Terminology (FAST) is a general use controlled vocabulary based on the Library of Congress Subject Headings (LCSH). FAST is developed as a part of WorldCat by the Online Computer Library Center, Inc. (OCLC), with the goal of making subject cataloging less costly and easier to implement in online contexts. FAST headings separate topical data from non-topical data, such as
