Evaluative bibliometrics compare the citation impact of researchers, research groups and institutions with each other across time scales and disciplines. Both factors, discipline and period – have an influence on the citation count which is independent of the quality of the publication....

A proposal is made in this paper for a broadening of perspective in evaluative bibliometrics by complementing the (standard) times cited with a cited reference analysis for a field-specific citation impact measurement. The times cited approach counts the citations of a given publication set. In...

A number of bibliometric studies point out that citation counts are a function of many variables besides scientific quality. In this paper our aim is to investigate these factors that usually impact the number of citation counts, using an extensive data set from the field of chemistry. The data...

More than 4,500 open access (OA) journals have now become established in science. But doubts exist about the quality of the manuscript selection process for publication in these journals. In this study we investigate the quality of the selection process of an OA journal, taking as an example the...

We have developed a (freeware) routine for “Referenced Publication Years Spectroscopy” (RPYS) and apply this method to the historiography of “iMetrics,” that is, the junction of the journals Scientometrics, Informetrics, and the relevant subset of JASIST (approx. 20%) that shapes the...

Examining a comprehensive set of papers (n=1837) that were accepted for publication by the journal Angewandte Chemie International Edition (one of the prime chemistry journals in the world) or rejected by the journal but then published elsewhere, this study tested the extent to which the use of...
