خلاصه	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.	Life history research is a qualitative method that captures the full arc of an individual's life — or a significant portion of it — through extended biographical interviewing and analysis of personal documents. Rooted in early Chicago School sociology, the method treats each life story as a window into broader social, cultural, and historical forces. The researcher and participant co-construct a narrative account that illuminates how personal experience is shaped by, and in turn shapes, wider social structures and processes.
