概要	Field-based document analysis is a qualitative strategy in which the researcher enters a real-world setting — a school, clinic, organisation, or community — and systematically collects, authenticates, and analyses documents that are naturally produced and used there. Unlike library-based or archival document analysis, the field context is integral: the researcher observes how documents function in practice, who produces and reads them, and what organisational or cultural work they perform. The approach is widely used in ethnographic, case-study, and institutional research.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.	Document analysis is a systematic qualitative research method for examining written, visual, or audiovisual sources—such as policy documents, historical records, organizational records, media reports, emails, social media posts, photographs, or videos—to extract meaning, identify patterns, and understand social phenomena. Developed by Weber and Mannheim in early 20th-century sociology, the method bridges historical research, content analysis, and textual interpretation. Document analysis is used across disciplines to understand organizational change, policy evolution, media representation, historical events, and cultural meaning. Documents provide evidence of what organizations, institutions, or societies value, decide, and communicate, often revealing contradictions between policy and practice.
