The sixth volume published, Volume IV, brought to completion the 18th century. Appearing in 1979, 504 biographies spanned the years 1771 to 1800. That same year, Volume I was reprinted with corrections. Volume II was also reprinted, with corrections, and the seventh volume appeared, both in 1982. Volume XI contained the biographies of 586 noteworthy Canadians who died between 1881 and 1890. A new feature was introduced in this volume: indexes by occupation and geography. This new feature was to be incorporated in new volumes and in reprints of previous volumes as well as separate indexes, one of which appeared in 1981 for Volumes I–IV.
