No matter where you find information that might send you in the right direction during your research, make sure to choose sources that are legitimate, reputable sources. Avoid websites that are unknown to you. Don't depend on some else's analysis of a legal issue unless it is peer-reviewed.
Scattershot web searches can give you ideas for legal words and phrases concerning your issue, as well as federal and state laws and news about pending legislation or court cases.
One thing is certain: the law is always changing.
Whatever you read online about a legal issue, even in a recent law review, might have already been changed, by a new law, regulation, or court case.
Find a blawg on your topic by a law professor or attorney, or legal non-profit that practices law concerning that issue. Then use their sources.
Organizations like the American Civil Liberties Union and the Southern Poverty Law Center have websites with information on the issues most important to their organization. They are certainly biased, but they can be a good place to start research because they will provide keywords and phrases that will help you with your searching. They may also talk about specific court cases.
Federal and state agencies often issue press releases about changes to regulatory law, statutory law, or case law.
