Database searching is good for looking for materials on a specific topic in many different journals at the same time.
These links will take you to a page that gives you access options for that specific journal title. Looking through a specific journal is good when you know they typically cover the issues in which you are interested or when you want to browse. Please note that the dates covered by the different access options might not be the same; choose the source that gives you the dates you need.
Newspapers can be good sources for information about current situations.
