Research Impact

Traditional ways to measure impact

Author

Traditional measures of author impact include the number of publications in your field and the number of times these publications have been cited by other researchers. Listed below are two common research metrics that use different algorithms to measure scholarly output.

Common tools for calculating research impact, including the h-index, are Web of Science, Scopus, and Google Scholar. Instructions for each of these tools can be found here.

 

Journal

The importance of a journal within a field and its impact are generally measured through the number of articles published per year and the number of citations to articles published in a particular journal. The table below lists some common ways of measuring journal impact.
