Google Scholar Citations is a great multi-disciplinary citation tracking tool for showing evidence of scholarly impact for promotion and tenure, as well as your CV or faculty page. In minutes, you can set up a customized page listing your works, citation counts, and h-index. You also have the option to include research interests and URLs of websites or other online content you have created.
To be notified when new publications cite any of the works in your profile, an alert can be created. Researcher profiles are searchable by name or research interest. Conversely, profiles are searchable in Google Scholar if set to public view.
