108 Assets: UNESCO ( 6-digit codes)
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. This page describes the 6-digit nomenclature (2.235 6-digit names).
