Scientometrics is one of the most common methods to measure scientific performance. In the 70s, this notion emerged in the former Soviet Union and Eastern Europe countries, especially Hungary, to measure sciences at national and international levels. “Scientometrics” was coined by Doborov and Karanwa[A1], who defined this term as the measurement of Informatics processes. According to Mikhailov, Informatics is the discipline of science, which evaluates the structure and properties of scientific information and discusses the regulations and processes of these connections.

Following the introduction of this science, other prominent scientists, such as Cole, Elles and Holmes, used scientific articles as a criterion for comparing different countries in terms of scientific production. Therefore, the first statistical analysis of scientific papers is attributed to these individuals, who applied the published scientific articles as a criterion for comparison of scientific production of various countries.

At the same time, individuals such as Lotka, Bradford, Ziff, proposed special theoretical models for evaluation of the distribution of publications based on authors and journals.

Despite many activities in this field of science, the objectives and techniques of scientometrics were not determined until 1969, when Nalimov and Molchenko defined the subsidiary fields of scientometrics and its scope of work.

Publication of the international scientometrics journal in 1978 by Tibor Braun was another important step toward the global recognition and development of this science. This magazine was published by Elsevier publications in Amsterdam, and the Hungarian Academy of Sciences in Budapest (which was the most active scientific community in this field) frequently published articles on scientometrics.
