Bornmann L, Daniel H D. Multiple publication on a single research study: Does it pay? The influence of number of research articles on total citation counts in biomedicine. Journal of the American Society for Information Science nad Technology. 2007; 58(8)
Scientists often seek to report a single body of research in more than one publication, in repeated reports of the same work or in fractional reports, in order to disseminate their research as widely as possible in the scientific community. Up to now, it has not been yet examined whether this strategy of multiple publication leads to greater reception of the research. The results of a regression model with an interaction term show that the practice of multiple publication does in fact lead to greater reception of the research even if reception is actually dependent upon length of article. Thus, according to the author, it pays for scientists to practice multiple publication of study results in the form of sizable reports.
