สรุป	Longitudinal historical archival research is a qualitative and documentary method that systematically examines primary archival sources — records, manuscripts, correspondence, institutional files — across multiple points in time to trace change, continuity, or development within a phenomenon over an extended historical period. By imposing a longitudinal dimension on standard archival inquiry, researchers can reconstruct how events, structures, policies, or social conditions evolved rather than capturing only a single historical moment.	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.
