Volume XII of the DCB said that the first three volumes of the 20th century were in preparation: Volume XIII (1901–1910); Volume XIV (1911–1918); Volume XV (1919–1925). But when Volume XIII appeared in 1994, with Ramsay Cook as new general editor, the intervening years were described as "hav been among the most difficult in the history of this Canadian institution." Severe financial restraints were described and a more "modest" plan was announced, with each volume covering a decade instead of the shorter intervals previously planned for post-1910. An additional volume was said to be in preparation up to the end of 1940.
