How Many Is Too Many? On the Relationship between Research Productivity and Impact.

In this research article, published in PLOS One, V. Larivière and R. Costas analysed the publication and citation records of more than 28 million researchers, who published at least one paper between 1980 and 2013. Based on this data base, the authors aimed to understand the relationship between research productivity and scientific impact: using the number of citations as a measurement for research quality, they addressed the question whether incentives for scientists to publish as many papers as possible will lead to higher-quality work – or just more publications. It was found that, in general, an increasing number of scientific articles per author did not yield lower shares of highly cited publications, or, as Larivière and Costas put it: ‘the higher the number of papers a researcher publishes, the higher the proportion of these papers are amongst the most cited.’ LINK
