Bibliometric indicators

Bibliometric indicators are mathematical-statistical tools used by citation databases to analyze the publications dissemination patterns and to quantitatively assess the impact of research within its disciplinary community. They came up in 1963 with the published the first SCI (Science Citation Index) by Eugene Garfield of the ISI - Institute for Scientific Information. Bibliometric indicators can be applied to individual researchers, journals, research groups, universities, or countries. Some indicators are created by publishers and commercial companies (such as Elsevier, Clarivate) and they are covered by copyright (for example, the Impact Factor can only be accessed through the Journal Citation Reports database, purchased by the university), while others are freely available, such as those from Publish or Perish.
