Databases index the contents of journals and are the first place you want to look for articles.
Law journals, also known as law reviews, are collections of peer-reviewed scholarly articles about the law. Law journals can be general in scope, or focused on a particular area of law or geographical region. Law journal articles can be helpful to consult in the first stages of research, because they will often summarize the law on a subject up to that point.
Public policy intersects with other subjects. Often policy-related articles are published in journals in other areas of research.
