• A few basic reasons for choosing a specific type of legal scholarship
Legal scholarship is authored by members of the academe, whether faculty members, or students, members of the academe auxiliary, law librarians, or even practitioners to explain what the law is in a particular area. They have an academic audience in mind (the pool that produced the authors), but can be used by practitioners as tools of persuasion.
If you know that you have a good grasp of the issues in question, and that you understand them sufficiently that searching for secondary sources will be meaningful and bring you a responsive source that covers your topic, then the next step is to learn how you can locate those commentaries about the law.

Indexes remain your best friend whether you use print (very unlikely) or online information. Nest sections discuss such tools.

Remember, Google is only a massive indexer of information!
