概要	Comparative document analysis is a qualitative research design that systematically examines two or more documents — or document sets — side by side to identify similarities, differences, patterns, and contradictions across contexts, institutions, time periods, or jurisdictions. Drawing on document analysis as a primary method, the comparative dimension adds analytical leverage by allowing the researcher to ask not just what a document says, but how and why it differs from comparable documents elsewhere.	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.
