概要	Legal content analysis applies the systematic procedures of content analysis to legal texts — statutes, regulations, judicial opinions, treaties, and legal commentaries — in order to identify patterns, themes, and trends across a corpus of legal material. It bridges qualitative legal scholarship and quantitative social-science methods, enabling researchers to draw reproducible, evidence-based conclusions about how law is written, applied, or has changed over time.	Case law analysis is a systematic method for examining judicial decisions to identify binding legal rules, evolving doctrines, and interpretive trends. Rooted in the common law tradition of stare decisis, it requires the researcher to locate the ratio decidendi — the binding reasoning — of each decision, distinguish it from obiter dicta, and trace how that reasoning has been applied, distinguished, or overruled across subsequent cases. The method is fundamental to legal scholarship, litigation strategy, and law reform research.
