ABSTRACT: This study uses two bibliometric methods, direct citation

and co-authorship, to investigate the interdisciplinary changes in

information sciences during 1978-2007. The disciplines of references and

co-authors from five information science journals were analysed.

Furthermore, Brillouin's Index was adopted to measure the degree of

interdisciplinarity. The study revealed that information science

researchers have cited the publications of library and information

science (LIS) most frequently. The co-authors of information science

articles are also primarily from the discipline of LIS, but the

percentage of references to LIS is much higher. This indicates that

information science researchers mainly rely on publications in LIS, and

they often produce scientific papers with researchers from LIS. The

discipline rankings generated by direct citation and co-authorship show a

significant consistency via Spearman's correlation coefficient test. The

interdisciplinary degree of information science has displayed growth. In

particular, the degree of interdisciplinarity for co-authors has grown.
