The Metrics Toolkit provides evidence-based information about research metrics across disciplines, including how each metric is calculated, where you can find it, and how each should (and should not) be applied. You’ll also find examples of how to use metrics in grant applications, CVs, and promotion dossiers.
An Overview of Metrics
Research impact indicators can be quantitative or qualitative. However, research impact metrics are quantitative and are diverse. Examples include citation-based metrics, such as citation counts, the h-index, the Journal Impact Factor, and normalized citation metrics, such as the Field-Weighted Citation Impact from Scopus. Normalized metrics allow you to compare citation impact across disciplines or fields, document type, and publication year.
