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.	Document analysis is a systematic qualitative research method for examining written, visual, or audiovisual sources—such as policy documents, historical records, organizational records, media reports, emails, social media posts, photographs, or videos—to extract meaning, identify patterns, and understand social phenomena. Developed by Weber and Mannheim in early 20th-century sociology, the method bridges historical research, content analysis, and textual interpretation. Document analysis is used across disciplines to understand organizational change, policy evolution, media representation, historical events, and cultural meaning. Documents provide evidence of what organizations, institutions, or societies value, decide, and communicate, often revealing contradictions between policy and practice.
