Until recently our knowledge of the B-decay coupling constants came principally from studies of the electron momentum distribution, the half-lives of B-emitters and the B-v angular correlation. With the discovery of the breakdown of parity conservation we have both an increase in the number of coupling constants and new tools for investigating B-decay. The great stimulus that this has given B-spectroscopists is evidenced by the profusion of papers and preprints which has appeared in the interval and which for a time caused frequent changes in the B-decay situation. In the past month or so since the Israel Conference this spate seems to have subsided somewhat and the situation seems now to be quasi-static.
