সারসংক্ষেপ	Comparative historical archival research combines systematic examination of primary archival sources across two or more historical cases — nations, regions, institutions, or time periods — to identify causal patterns, structural similarities, and divergences that single-case histories cannot reveal. It is the method of choice when researchers want to explain why similar or different outcomes emerged across distinct historical contexts using documentary evidence.	The oral history method is a qualitative research approach in which researchers conduct in-depth, recorded interviews with individuals who have direct personal experience of a historical event, social process, or community life. It captures subjective perspectives, memory, and lived experience that written records rarely preserve, making it indispensable for recovering voices absent from official archives — particularly those of marginalised communities, minority groups, and ordinary people.
