概要	Doctrinal legal research is the foundational methodology of legal scholarship. It systematically identifies, reads, and analyses authoritative legal sources — statutes, case law, constitutional texts, and regulations — to describe, explain, and critique the content and internal logic of legal doctrine. By working within the accepted hierarchy of legal sources, it answers the question 'What is the law?' with analytical rigour and interpretive precision, producing descriptions of settled doctrine and arguments for how ambiguities should be resolved.	Textual criticism is a systematic philological method for identifying, comparing, and evaluating variant readings across multiple manuscript or print witnesses of a text in order to reconstruct the most accurate version of the original — or the author's intended — text. Applied since antiquity to classical, biblical, and literary works, it remains the foundational editorial method in classical studies, biblical scholarship, medieval studies, and critical editing of literary works.
