Many databases let you create accounts and set up search alerts. A search alert will let you save search strategies and you can elect to receieve an optional email when new articles are added to the database. The databases listed below have this feature.
Many databases and journals will let you create RSS feeds for searches (similar to email search alerts) and journals. You can use a feed reader (like Google Alerts) to subscribe to feeds and access them with your google account. I've embedded a few journal table of contents feeds into this libguide for your convenience. If you'd like to know more about setting these up you can contact me for a library housecall.
