Melbourne, Melbourne University Press, first published between 1966 and 2007 (earlier volumes here are reprints).
Octavo, 19 volumes, with approximately 500-600 pages in each volume (and approximately 300 pages in the Index) plus various corrigenda and addenda leaves loosely inserted in most volumes.
Cloth; a fine set with the fine (royal blue) dustwrappers.
Offered with the two-volume companion set, 'A Biographical Register, 1788-1939. Notes from the Name Index of the Australian Dictionary of Biography', compiled and edited by H.J. Gibbney and Ann G. Smith (Canberra, 1987; octavo, approximately 400 pages per volume; card covers slightly rubbed; an excellent set). The online edition has compromised the price of the printed version, but these sets remain invaluable.
