Erratum.
In the article "Bloch prepares NSF for lean years" by John Walsh (News & Comment, 25 Apr., p. 440), the labels for "Coordinated research" and "Large projects" were inadvertently reversed in a chart depicting the breakdown of the fiscal year 1986 National Science Foundation budget. Coordinated research accounts for 14% of total research, and large projects account for 20%. A corrected chart is shown below. [See Chart in Source PDF].
