A table of contents alert will send you the table of contents (TOC) for new issues of your favorite journals. Alerts may be sent via email or RSS feed. There are several ways to sign up for alerts including directly from the journal publisher, databases or other services.
Many journals offer table of contents alerts. Go directly to the journal publisher's website and look for links such as New Issue Alert, TOC Alert, or Email Alert.

Another method to receive TOC alerts is through an independent service. JournalTOCs is the largest collection of scholarly journal TOCs. Sign up for a free account and receive alerts via email or RSS feed.
