The awarding ceremony of the Derek de Solla Price Memorial Medal has become an essential part of the programme of ISSI conferences since the foundation of the Society in 1993. The Price Medal was conceived and launched by Tibor Braun, founder and Editor-in-Chief of the international journal Scientometrics, and is periodically awarded by the journal to scientists with outstanding contributions to the fields of quantitative studies of science. The journal Scientometrics is an international journal for all quantitative aspects of the science of science, communication in science and science policy co-published by Akadémiai Kiadó, Budapest, and Kluwer Academic Publishers, Dordrecht.
