Having research papers and other scholarly writing available online gives researchers access to a great deal of materials without having to enter a library. But how does this impact the new research that they produce? James Evans at the University of Chicago has studied this question and his conclusion is surprising--despite having greater access to scholarly materials, researchers are actually citing fewer papers. The papers they do cite tend to be newer and are likely to be cited by other researchers.

Thanks to the Internet, scientists now have access to an astonishing number of research papers, scholarly journals and other papers. But according to new research conducted by James Evans, a professor sociology at the University of Chicago, researchers are actually citing fewer papers than ever, and they tend to cite newer papers that are also cited by many of their peers. In this interview, James discusses what got him interested in the topic, how he conducted his research and what he believes are some of the implications of this trend.
