6-digit UNESCO Nomenclature
UNESCO Nomenclature (more properly UNESCO nomenclature for fields of science and technology) is a system developed by UNESCO for classification of research papers and doctoral dissertations. There are three versions of the system, offering different levels of refinement through 2-, 4-, and 6-digit codes.
The following links do not link directly to topics. Instead, they link to pages on which the 6-digit UNESCO nomenclature is described in more detail: it is far too large a system to cover on a single page.
