Most academic databases allow you to set up RSS feeds or e-mail alerts for individual journals or searches (keywords, etc.). These allow you to keep current of new publications in your field without having to regularly repeat multiple searches.
JournalTOC is a free service that collects feeds from over 19,000 academic journals, and can provide you with new tables of contents whenever a new issue is published. Browse by subject area, journal title, or combine multiple journal titles into a single feed!
