תקציר	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.	Triangulated Field Notes is a qualitative data collection technique in which field notes are recorded independently by multiple observers, from multiple vantage points, or at multiple time points and then systematically compared to strengthen the credibility and completeness of observational data. Rooted in Denzin's triangulation framework and Lincoln and Guba's trustworthiness criteria, the approach counters observer bias by cross-checking accounts before analysis begins.
