Bibliometrics, scientometrics, infometrics, and librametrics are analogous terms that represent measuring techniques in library and Information science that are mainly applied in solving various problems pertaining to library and Information sciences1.
Bibliometrics
Bibliometrics is defined as the study and measurement of the publication patterns of all forms of written communication and their authors2.
Scientometrics
Hystorically, scientometrics was led by such fundamental questions 'why should we not turn the tools of science on science itself?' and 'why not measure and generalize, make hypotheses, and derive conclusions?'3. Those questions have led how scientometrics are generated nowadays4.
