This guide covers the library resources central to identifying impact factors that can be used in the narrative of a promotion and tenure dossier. It is important to remember that there is no one size fits all approach to metrics across disciplines. Use the information that documents the impact you want to demonstrate.
Explore the areas that work best for you and schedule a consultation with Deborah Williams, Ed.D, Scholarly Communication Librarian, for additional assistance.
Note there is a glossary of terms at the bottom of this page that will help define each metric.
