One of the regular tasks at Dewey Manor is to map new Canadian Subject Headings (CSH) to Dewey numbers. In the March 2006 list were "Painting, French-Canadian" and "Painting, French-Canadian--Québec (Province)"; these headings present an interesting issue of Dewey application.
Both headings contain facets for the ethnic group (French Canadians) and for place (Canada or Québec), even if Canada is only implicit in the "Painting, French-Canadian" heading. If we were just building numbers using Table 1, then the table of preference for that table puts ethnic groups (--089 within --08) ahead of places (--093-099). However, for 750 Painting and paintings, geographic treatment is displaced to 759. That means the rule of zero comes into play, since "there is a choice between the 0 subdivision and subdivisions beginning with 1-9 in the same position in the notation." (DDC Glossary) 750.89114 French-Canadian painting has a zero after the 75, while 759.11 Canadian painting and 759.114 Québec painting do not, so we prefer the numbers without the zero, i.e., 759.11 or 759.114
However, in 759.1-759.9, we can add a standard subdivision from Table 1 (with a few exceptions for works about individual painters, which do not apply here). So to those numbers we can add --089 Ethnic and national groups from Table 1, and --114 Canadians of French origin from Table 5, giving, for "Painting, French-Canadian" the full number 759.11089114, and for "Painting, French-Canadian--Québec (Province)" the full number 759.114089114.
