Since its beginning thirty years ago, bibliometrics has mainly studied
academic publications. More often, the Science Citation Index (SCI) i
s treated as a whole, without breakdown of papers by sectors (universi
ty, government, industry). However, between 15% and 30% of the SCI pub
lications comes from other sectors than university. We present the fir
st bibliometric analysis of papers broken down by sectors. The data ha
ve been used to test the following hypothesis: the share of papers by
sectors other than university is increasing, while university's share
is decreasing. The hypothesis is tested for Quebec over the period 198
0-1990. It appears that it is true that the share of papers by sectors
other than university is increasing. And this is so at a rate greater
than that of university's growth. Quebec's university sector has decr
eased its share of papers over the ten-year period from 89.2% to 85.1%
. However, university remains the top sector in terms of papers and re
mains the main partner of each sector in terms of cosignatures.
