The first volume of the Australian Dictionary of Biography appeared in 1966, the sixteenth in 2002, by which stage the series included persons who had died prior to 1981. This one-volume Supplement includes those who were for one reason or another omitted from the main volumes. It is an impressive achievement. There are 504 biographies, written by 399 authors. Almost all are well written and carefully researched, with up-to-date lists of sources. The editor and his associates have had the Herculean task of melding all these biographies into a work of reference in which the entries have a consistency in the type of information presented, while at the same time allowing for the individuality of each subject and author. In this, they have succeeded admirably. The volume has the air of authority.
