Leiden Ranking is produced by the Centre for Science and Technology Studies at Leiden University. It provides a variety of bibliometric indicators and is highly regarded by the international research community. In recent years it has added measures of gender equity and open access.
The indicators are derived from the Web of Science database, including publications in the social sciences and the humanities.
This current edition shows that with regard to the output of research, the lead of Harvard is steadily being whittled away. The top ten universities according to the number of publications over the period 2017-2019 include eight Chinese universities, plus Harvard still in first place and the University of Toronto in fourth.
The picture is different when we look at the percentage of papers in the top 10% of journals, which is a measure of the quality of research publications. Here the top ten is led by Rockefeller University, a specialist medical institution, followed by MIT and Princeton. The best performing Chinese university is Hunan University in 14th place.
It is likely that the Open Access and Gender Equity metrics will arouse a lot of interest. In the current edition the leading university for the percentage of open access publication is the London School of Hygiene and Tropical Medicine, followed by Bilkent University and the University of East Anglia and the top of the table is dominated by British institutions. Scottish universities are especially well represented with Dundee, Stirling, Glasgow, St Andrew’s, and Strathclyde in the top twenty.
The table for Gender Equality (female authors as a percentage of male and female authors) is dominated by Eastern European, especially Polish, institutions. The first place is held by the Medical University of Bialystock, followed by the Lithuania University of Health Science, and Warsaw University of Life Science.
