It's always nice to get a heads up on something of interest to you, isn't it? You can get emails alerting you about articles in your areas of interest from several different databases we have. The biggest one probably is Ingenta, which covers over 30,000 different publications. ScienceDirect has such a service too, as does HighWire Press.
With each of them you simply need to register (it's free) then set up your alert to search for those subjects you are interested in.
