Before starting library research (or searching Google) it is very important that you take sufficient time to identify the kind of issues that interest you and/or that you feel passionate about. This is also true when you are choosing a research topic. If you are not sure what the current issues are that people are concerned about, you may browse the sources listed on the right. These sources normally list current (some are historical) public interest issues. Some are research resources for journalists and some are collections of public speeches delivered in recent months (and years going all the way back into the 1930s). Browse these sources and see what triggers your interest.
CQ Researcher Focuses on a specific topic that is perceived as being either newsworthy or an issue of broad interest in the public policy sphere. Recent examples are on "Curbing CEO Pay" and "Re-examining the Constitution".
