Correction: omitted author.
Through an inadvertent error on my part, I neglected to include the name of one author-Giovina Ruberti-of the report "Requirement for CD8(+) cells in T cell receptor peptide-induced clonal unresponsiveness" (1 Jan., p. 91). The correct order of the authors is as follows: Amitabh Gaur, Giovina Ruberti, Richard Haspel, John P. Mayer, and myself.
