The 1998 adjustment of the values of the fundamental physical constants has been carried out by the authors under the auspices of the CODATA Task Group on Fundamental Constants [1,2]. The purpose of the adjustment is to determine best values of various fundamental constants such as the fine-structure constant, Rydberg constant, Avogadro constant, Planck constant, electron mass, muon mass, as well as many others, that provide the greatest consistency among the most critical experiments based on relationships derived from condensed matter theory and quantum electrodynamics (QED) theory. The 1998 CODATA recommended values of the constants also may be found on the Web at physics.nist.gov/constants.

The values of the fundamental constants and the theory of quantum electrodynamics (QED) are cl< ely coupled. This is evident from the fact that the constants appear as parameters in the theoreticjd expressions that describe the physical properties of particles and matter, and most of these theoretical expressions are derived from QED. In practice, values of the constants are determined by a consistent competrison of the relevant measurements and theoretical expressions involving those constants. Such a comparison is being carried out in order to provide CODATA recommended values of the constants for 1997. This review describes some of the advances that have been made since the last set of constants was recommended in 1986. As a result of these advances, there is a significant reduction in the uncertainty of a number of constants included in the set of 1997 recommended values. 

An adjustment of the fundamental constants is underway to provide the CODATA 1997 recommended values. The results of this work will be described in a report of the CODATA Task Group on Fundamental Constants written by Barry Taylor (NIST), E. Richard Cohen (Rockwell Int, retired), and the present author. 

The most recent adjustment gives the current CODATA recommended values as reported by E. R. Cohen and B. N. Taylor, The 1986 adjustment of the fundamental physical constants , Rev. Mod. Phys. 59, 1121 (1987). 

In 1990, the effect of new information on the fundamental constants was examined by B. N. Taylor and E. R. Cohen, Recommended values of the fundamental physical constants A status report , J. Res. Natl. Inst. Stand. Technol. 95, 497 (1990).
