Committee on Data for Science and Technology (CODATA)

A committee set up by the International Council of Scientific Unions in 1966 to improve the compilation, critical evaluation, storage and retrieval of data of importance to science and technology. The committee consists principally of representatives of the various national standards laboratories, as well as the BIPM. CODATA periodically issues reports identifying the best current values for the principal physical constants, and also for certain conversion factors. For current CODATA values, see physics.nist.gov/constants

A very good article on the origin and nature of the CODATA set of constants is
