The tools that are described in this guide for measuring impact through h-index and citation count include Google Scholar, Researcher ID and Scopus ID. Google Scholar requires a free Google account to use where Researcher ID and Scopus ID require your PSU access ID to log in. All three options require users to verify that relevant publications are included in your ID.
- Publication Counts (can include all works)
Refers to the total number of works (articles, patents, book chapters, data sets, etc.) authored or co-authored by an individual. This measures amount of output and not the impact of that output.
The number of times a researcher has cited a journal article / book / data set / etc. in scholarly material. Highly cited works are often regarded as high quality and significant.
An author's h-index is a way of measuring a researcher's productivity and impact in a single value. An h-index is "n" number of articles that have been cited at least "n" number of times. Researchers with higher h-indexes are generally thought of as more prolific, as they have more output (publications) and impact (citations).
