The observed absence of quasar redshifts larger than 3.53 is erroneously attributed to Richard Green and myself in "A boundary for the quasars" (Research News, 22 Jan., p. 388). Our survey of bright quasars does not cover redshifts larger than 2.2 because in choosing candidates we rely on the ultraviolet excess, which tends to disappear at larger redshifts.
