สรุป	Historical archival research is a systematic method of investigating the past through the critical examination of primary source documents preserved in archives, libraries, and institutional collections. Researchers locate, access, authenticate, and interpret original records — such as government documents, correspondence, diaries, maps, and institutional files — to reconstruct events, trace processes, and build evidence-based historical arguments. It is foundational to historiography and widely applied across humanities and social science disciplines.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
