Researchers regularly follow the most important journals of their disciplines as well as current research topics and trends. There is often a need to follow current publications related to their own discipline, and, for example, the citations found for a certain article in the databases. For this purpose, databases and different services provide current awareness tools that are easy to use. Users can, for example, automatically be informed of new hits for their search, or the newest contents page of a journal in their email or alternatively have an RSS -feed to their computer's web browser.
