요약	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.	Comparative discourse analysis examines how language constructs meaning, identity, and power by systematically contrasting texts or speech acts drawn from at least two distinct contexts, groups, time periods, or institutions. By holding analytical categories constant across cases, it reveals how discursive patterns diverge or converge, producing insights that single-context discourse analysis cannot generate.
