Résumé	Comparative oral history collects and systematically compares first-person spoken testimonies from two or more distinct groups, communities, or historical contexts. The method blends the interpretive depth of oral history — privileging personal memory and narrative — with the analytical logic of comparative design, enabling researchers to identify both shared patterns and meaningful differences across the groups under study.	Comparative case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify similarities, differences, and patterns across contexts. Rooted in Yin's replication logic and Stake's multiple case framework, it is particularly suited to questions that ask how or why a phenomenon unfolds differently — or similarly — across distinct settings, populations, or time periods.
