Faculty can receive notifications when their articles are cited by signing up for various citation alert services.
On HeinOnline, faculty can sign up for email alerts in their HeinOnline author profile page for whenever their articles on Hein are cited by new publications and cases on Hein. View instructions on how to manage author alerts from HeinOnline here: https://help.heinonline.org/kb/how-to-manage-author-alerts/.
You can make a Google Scholar profile and receive alerts any time your articles on Google Scholar are cited by other works in Google Scholar. You can read more about Google Scholar profiles and how to receive alerts here: https://scholar.google.com/intl/en/scholar/citations.html#citations. If you need help making your Google Scholar profile, see the screencast made by the BYU Law Library here: http://huntersquery.byu.edu/google-scholar-profiles/.
