Many of the library's databases will allow you to create email alerts or RSS feeds to notify you automatically when new articles are added. For example:
See how to set up search alertsin an EBSCO database.
See how to createsearch alertsin a ProQuest database.
NOTE: these alerts will send you new articles, etc. based upon the keywords that you used to search for your topic. Make sure that you are using the best possible keywords, in order to see the best possible results.
