The relationship between usage and citations in an open access mega journal

Authors : Barbara McGillivray, Mathias Astell

How does usage of an article relate to the number of citations it accrues? Does the timeframe in which an article is used (and how much that article is used) have an effect on when and how much that article is cited?

What role does an article’s subject area play in the relationship between usage and citations? This paper aims to answer these questions through an observational study of usage and citation data collected about a multidisciplinary, open access mega journal, Scientific Reports.

We find that while the direct correlation between usage and citations is only moderate at best, the relationship between how early and how much an article is used and how early it is cited is much clearer. What is more, we find that when an article is cited earlier it is also cited more often, leading to the assertion that if an article is more highly accessed early on, it is more likely to be cited earlier and more often.

As Scientific Reports is a multidisciplinary journal covering all natural and clinical sciences, this study was also able to look at the differences across subject areas and found some interesting variations when comparing the major subject areas covered by the journal (i.e. biological, Earth, physical and health sciences).

Evolution of the scholarly mega-journal, 2006–2017

 Author : Bo-Christer Björk

Mega-journals are a new kind of scholarly journal made possible by electronic publishing. They are open access (OA) and funded by charges, which authors pay for the publishing services. What distinguishes mega-journals from other OA journals is, in particular, a peer review focusing only on scientific trustworthiness.

The journals can easily publish thousands of articles per year and there is no need to filter articles due to restricted slots in the publishing schedule. This study updates some earlier longitudinal studies of the evolution of mega-journals and their publication volumes.

After very rapid growth in 2010–2013, the increase in overall article volumes has slowed down. Mega-journals are also increasingly dependent for sustained growth on Chinese authors, who now contribute 25% of all articles in such journals.

There has also been an internal shift in market shares. PLOS ONE, which totally dominated mega-journal publishing in the early years, currently publishes around one-third of all articles. Scientific Reports has grown rapidly since 2014 and is now the biggest journal.
