Abstract

The Internet has substantially increased the online accessibility of scholarly publications and allowed researchers to access relevant information efficiently across different journals and databases (Costa & Meadows, ). Because of online accessibility, academic researchers tend to read more, and reading has become more superficial (Olle & Borrego, ), such that information overload has become an important issue. Given this circumstance, how the Internet affects knowledge transfer, or, more specifically, the citation behavior of researchers, has become a recent focus of interest. This study assesses the effects of the Internet on citation patterns in terms of 4 characteristics of cited documents: topic relevance, author status, journal prestige, and age of references. This work hypothesizes that academic scholars cite more topically relevant articles, more articles written by lower status authors, articles published in less prestigious journals, and older articles with online accessibility. The current study also hypothesizes that researcher knowledge level moderates such Internet effects. We chose the "IT and Group" subject area and collected 241 documents published in the pre-web period (1991-1995) and 867 documents published in the web-prevalent period (2006-2010) in the Web of Science database. The references of these documents were analyzed to test the proposed hypotheses, which are significantly supported by the empirical results.

Abstract

To explore the possible facilitative role of the Internet in the process of research collaboration, this study endeavored to systematically compare the phenomenon of co-authorship and the impacts of co-authorship between pre-web and post-web stages in the field of information systems. Three hypotheses were proposed in this study. First, research collaboration increases in the post-web stage relative to the pre-web stage. Second, research collaboration is positively related to research impact, operationally defined as the number of citations. Lastly, the positive relationship between research collaboration and research impact is stronger in the post-web stage than that in the pre-web stage. Articles published in the field of information systems in both time periods were collected to test the hypotheses. The empirical results strongly support H1 and H2, showing that co-authorship increases in the post-web stage, and positively correlates with citations received by information systems articles. The positive effects of interdisciplinary collaborations and collaborations among multiple authors are enhanced in the post-web stage, but such enhancement is not found for international collaboration. H3 is partially supported.
