Fourth volume in the annual series, and once again the work--articles, commentary, criticism--proves exemplary. From the headline-making exposÉ by Tamar Stieber (The Albuquerque Journal) of the fatal effects of L-Tryptophan to the investigation by Gilbert M. Gaul (The Philadelphia Inquirer) of exactly what happens to donated blood, this is journalism at its committed best, with each selection, as always in this series, introduced and placed in context by the prize-winner.
