RSS is a good source to keep up with journal articles as they come out. As a graduate student, one should read lots of journals and keep up with the daily issues. One way is to sign up in the related websites. Once you have the list of journals, you can subscribe to the website or be a member of the professional organization to access them. Many databases exist that hold certain issues of publications. Most of them facilitate subscription via email or RSS. If you subscribe by email, you can receive alerts for updates and track new publications. It is a matter of being more comfortable with what type.
