Table of contents services (also called Alerts and RSS feeds) are designed to keep you up-to-date with information about the latest journal publications and Internet-based resources as it becomes available.
Most journals and databases offer this service. To find out how to set up these services, go to the appropriate database (from the A-Z Indexes list) and look for links such as Web alerts, RSS feeds, Search alerts. In many cases you will be required to set up an account (My Research etc.) to have access to these alerting services.
