The review process is essential to the maintenance of high scientific standards in a journal. The efforts of individual referees are remarkable, and we take this opportunity to acknowledge publicly those who contributed reviews during the period that volume 120 was in preparation (reviews completed between 1 June 2002 and 30 June 2003). The memorials were solicited and managed by C. Stuart Houston. Individuals who contributed two or more reviews are signified by an asterisk.
