Part of reseachers' information retrieval skills is to keep up with the news and trends of their discipline. There are several databases and services and different kinds of tools to follow news, subscribe recent articles or, say, get announcements when your own paper has been cited. Usually it is simple and free to register for these services if they are purchased e.g. by the library. It could also be useful to follow non-refereed sources as social media profiles, science popularizing publications and blogs.
