The article is based on the results of the recently published report An International Comparison of the Quality of Academic Publication Output in the Czech Republic by the IDEA institute at CERGE-EI. Unlike most similar international bibliometric comparisons, ours does not only indicate the overall quantity of research publications noted in the Web of Science database, but also the quality of these publications. This enables us to compare Czech research fields both in terms of overall output and in terms of excellent output. We are also able to show how the international standing of Czech research fields has changed over time, the authors say.
