The following databases have a feature of performing a search, saving the search, then setting up an alert. Once you have a search on your topic that provides articles that are on your topic, you may save the search, then set up an alert. An alert is set up to send you any new articles that are on your topic as the new article is added to the specific databases. Each interface allows you to customize how often you get an alert.
Note: Although alerts are available in the interface for Factiva, it is not functional for educational accounts.
