Note that only audio was recorded for this session, but the PDF of the presentation is available here for you to follow along: Elana Broch: Impact Factors
You may have noticed journals’ announcements of their “impact factor” on their home page. “We’re number 1” sounds good, but what does it really mean? I’ll begin with a quick overview of Web of Science, the database that forms the basic for the calculations of the impact factor, show how impact factor is calculated, and the factors that influence its interpretability. Finally, we’ll discuss alternatives to the impact factor.
