Tóm tắt	Information Encountering Analysis, developed by Sanda Erdelez and articulated in her 1999 Bulletin of the American Society for Information Science article 'Information encountering: It's more than just bumping into information,' studies how people acquire useful information by accident — while searching for something else, or while not searching at all. Against the dominant picture of information behaviour as goal-directed seeking, Erdelez foregrounds serendipitous, incidental discovery as a distinct and important mode. She models an encounter as a sequence of functional steps — noticing, stopping, examining, capturing and returning — and classifies people by how readily they encounter information, from non-encounterers to 'super-encounterers' who experience and exploit accidental discovery frequently. The framework gives a vocabulary and analytic structure for a phenomenon long dismissed as mere luck.	The Critical Incident Technique (CIT), set out by John Flanagan in his 1954 Psychological Bulletin article, is a flexible set of procedures for collecting first-hand accounts of specific, observable incidents that were especially helpful or unhelpful in achieving some aim, and content-analyzing them to understand effective and ineffective behaviour. In library and information science it has become a widely used method for studying information seeking and use: instead of asking people in the abstract how they look for information, researchers ask them to recount concrete recent episodes — a time they urgently needed information, succeeded or failed to find it, encountered a barrier, or used a source to good or ill effect. Analyzing many such incidents yields grounded categories of information needs, behaviours, barriers and source roles. A 2025 Libri review documents the technique's broad application across LIS information-behaviour research.
