สรุป	Comparative historical archival research combines systematic examination of primary archival sources across two or more historical cases — nations, regions, institutions, or time periods — to identify causal patterns, structural similarities, and divergences that single-case histories cannot reveal. It is the method of choice when researchers want to explain why similar or different outcomes emerged across distinct historical contexts using documentary evidence.	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.
