요약	Multi-source field notes is a data collection approach in which two or more observers, sites, or vantage points contribute written records of naturally occurring events, interactions, and settings. By pooling notes from multiple sources, researchers cross-check individual impressions and capture aspects of a scene that any single observer would miss, strengthening descriptive richness and analytical trustworthiness.	Multi-source document collection is a data-gathering strategy in which researchers systematically locate, retrieve, and compare documents drawn from two or more independent sources — such as government archives, institutional records, media outlets, organisational reports, or digital repositories. By assembling evidence from diverse provenance, researchers can triangulate findings, detect discrepancies, and build a richer, more credible picture of the phenomenon under study than any single documentary source can provide.
