H-index is a popular author-level metric defined as a function of an author's productivity (number of publications) and impact (number of citations to these publications).  

Most popular sources of h-index values for authors are citation databases such as Web of Science and Scopus (both databases allow you to group publications by a specific author and provide basic metrics associated with these publications, including h-index).  If an author has a Google Scholar Profile, their h-index will be displayed in that profile. 

Note that h-index values will vary depending on the source of data.  An h-index value derived by Google Scholar is usually the highest for most authors, as it tracks citations from a wide range of sources.  Web of Science and Scopus-calculated h-index values are based on citations only from sources that they index.  

For more information on how h-index is calculated and where to find it see our LibGuide on bibliometric indicators of impact, or contact Bibliometrics Services Group at ULS.
