สรุป	Multiple case-based oral history is a qualitative research design that embeds oral history interviews within a multiple-case framework. Rather than collecting testimonies from a single community or site, the researcher deliberately selects two or more distinct cases — communities, cohorts, organisations, or geographic sites — gathers in-depth oral testimonies within each, and then conducts systematic cross-case comparison to identify both shared and divergent historical experiences.	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.
