The starting point for a public health law research study is the careful and credible measurement of law itself. The resources in this section discuss how to conduct legal research and the coding of statutes, regulations and cases in a transparent and reproducible manner.  

How to Write a Legal Mapping Paper

A legal mapping paper (sometimes called a “50 state survey”) reports the results of research to identify the key provisions of law on a particular issue, identifies patterns in the nature and distribution of laws, and defines important questions for evaluation research, legal analysis and policy development. The 50-state survey has a long history in public health law, but scientific legal mapping papers now set the standard for legal mapping work.

Coding Case Law for Public Health Law Evaluation

This monograph explores the special considerations in coding text when the relevant legal materials are judicial decisions. The content of case law merits careful study not simply because judicial opinions reflect or respond to the law, but because they are the law. But, more than this, judicial opinions are detailed repositories that show what kinds of disputes come before courts, how the parties frame their disputes, and how judges reason to their conclusions.
