Although bibliometrics and research evaluation seem to be almost identical, bibliometrics is an autonomous discipline that can have various forms when used as an instrument of quantitative research evaluation. The quantitative evaluation of publication and citation data is now performed in almost all nations around the globe. This is done for various purposes and by various stakeholders. Bibliometrics is used in research performance evaluation, especially in university and government labs, and is also used by policymakers, research directors and administrators, information specialists and librarians, and researchers themselves.
