Most databases, and some individual journal titles, now offer user alerts as a current awareness service. These alerts can be emailed to you or sometimes fed into an RSS reader, and will let you know when a new article has been added that fits your set search parameters. Usually, you can set up more than one subject alert within a single database.
For example, to set up a search alert in any of the EBSCOhost databases DePaul subscribes to, like Humanities Abstracts or MLA, you would first need to create a free My EBSCOhost account and sign in. Once signed in, any set of search results will have an Alert/Save/Share option. You can set up a new alert, set alert limits (how often you want to receive alerts, what format, etc.), and wait to be notified when a new article in your area of interest is added.
Alerts can be configured for all EBSCOhost and ProQuest databases, as well as IngentaConnect titles and many other journals. Just look under My Account for alert options, or ask your subject librarian or at a Reference Desk for help.
