Investigation 1
Since we were unable to use the OPAC of Nihon University, during the investigation period, we excluded
the university and used the top 2-11 universities as samples. The results of investigation 1 are shown in Table 1.
For instance, we can see that Chuo University library had 65 books whose titles or subtitles included “exercise
physiology”. Comparing the average number of holdings of the upper (top 2-11 universities) and lower (top
12-21 universities) universities, we may say that the former is larger than the latter. For instance, the average
number of holdings of books whose titles or subtitles included “biomechanics” in the upper and lower
universities were 44.0 and 26.5, respectively (see Table 1).
