This article summarizes the preliminary findings from a recent study of sci
entists in four disciplines with regard to computer-mediated communication
(CMC) use and effects. Based on surveys from 333 scientists, we find that C
MC use is central to both professional and research-related aspects of scie
ntific work, and that this use differs by field. We find that e-mail use fo
cuses on coordination activities, and its biggest effect is helping to inte
grate scientists into professional networks. We do not find gender differen
ces in use, but there is some evidence that e-mail is having a differential
, positive effect for women. Furthermore, CMC use is positively associated
with scientific productivity and collaboration.
