This document provides guidance on the use of several indicators (sometimes called metrics) used in research assessment: the Journal Impact Factor and other measurements of journals, citation counts, h-index, field-normalized citation indicators, and altmetrics. Five principles guide the use of these metrics: be clear, be transparent, be specific, be contextual, and be fair.
