This paper presents an overview of research assessment methodologies developed in the field of evaluative bibliometrics, a subfield of quantitative science and technology studies, aimed to construct indicators of research performance from a quantitative statistical analysis of scientific-scholarly documents. Citation analysis is one of its key methodologies. The paper illustrates the potentialities and limitations of the use of bibliometric indicators in research assessment. It discusses the relationship between metrics and peer review; databases used as sources of bibliometric analysis; the pros and cons of indicators often applied, including journal impact factors, Hirsch indices, and normalized indicators of citation impact; and approaches to the bibliometric measurement of institutional research performance.
