สรุป	Historical archival research is a systematic method of investigating the past through the critical examination of primary source documents preserved in archives, libraries, and institutional collections. Researchers locate, access, authenticate, and interpret original records — such as government documents, correspondence, diaries, maps, and institutional files — to reconstruct events, trace processes, and build evidence-based historical arguments. It is foundational to historiography and widely applied across humanities and social science disciplines.	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.
