Partial correlations from the Wisconsin (Smith, 2006) study indicate significant positive
correlations at all three levels using a variety of community and school control variables (see
Table 7). In the Illinois study (Lance et al., 2005), again, actual numbers were not reported, but
in partial correlations that included school and community variables, size of the collection was
significant at the high school level with two of four of the control variables, and significant in
grades 5 and 8 with three of the four control variables.
