We report on our findings regarding authors' use of theory in 1,160 article
s that appeared in six information science (IS) journals from 1993-1998. Ou
r findings indicate that theory was discussed in 34.1% of the articles (0.9
3 theory incidents per article; 2.73 incidents per article when considering
only those articles employing theory). The majority of these theories were
from the social sciences (45.4%), followed by IS (29.9%), the sciences (19
.3%), and humanities (5.4%), New IS theories were proposed by 71 authors, W
hen compared with previous studies, our results suggest an increase in the
use of theory within IS. However, clear discrepancies were evident in terms
of how researchers working in different subfields define theory. Results f
rom citation analysis indicate that IS theory is not heavily cited outside
the field, except by IS authors publishing in other literatures. Suggestion
s for further research are discussed.
