Current awareness services, including tables of contents, new books, search, and citation alerts, will help you to stay informed when new information is published in your area of interest. Once you set up an account, the information is pushed at a specified frequency (daily, weekly, monthly) via email or an RSS feed. You usually need to set up a free account/profile to receive alerts.
Reasons to have alert services:
Search alerts allow you to be notified when results matching your search criteria are added to the database.
Summon offers RSS feeds for specific searches, without creating a login or an account.
Once you create a search and narrow it to your specifications, use the RSS button to add it to your feed reader.
Some databases below require that you create a profile or account in order to store your searches. You can then create an email alert or RSS feed so that any new articles that meet your search criteria are sent to you.
