A previous issue of this journal carried a selective report of the International Symposium on Metal-Hydrogen Systems, Fundamentals and Applications, held in Banff, Canada, September 2^nd–7th, 1990, (R.-A. McN., Platinum Metals Rev., 1991, 35, (1), 24–27). The papers presented at that meeting, including those in the special sessions on hydrogen pairing in metals, have now been published in the Journal of the Less-Common Metals, 1991, 172–174, Parts A and B.
