Some article databases, such as Scopus and Web of Science Core Collection, provide email citation alert service so that information of new articles citing your chosen articles can be sent to you automatically via email. Sometimes, alerts can be provided by RSS feed.
This page assists you to set up email citation alerts and RSS citation alerts.
Note that a citation alert allows you to track when an article has been cited. However, the availability of new citations depends on the databases you are using. So it is unlikely that all citations will be tracked with the citation alerts you created.
The ways of setting up of citation alerts differ in different databases. Below are steps generally applicable to most databases.
Step 1: Locate the article you want to track by searching or browsing and then view the full record.
Step 2: Click "Create citation alert", "Set citation alert", "Alert me when this article is cited", "Citation alert", "Alerts", "E-mail alerts", etc., depending on the database you are using.
