概要	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.	Everyday Life Information Seeking (ELIS), introduced by Reijo Savolainen in his 1995 article in Library & Information Science Research, shifts the study of information behaviour away from work and professional tasks toward the ordinary, non-work information practices of daily life. Savolainen explains these practices through two linked concepts borrowed in part from Bourdieu: 'way of life,' the taken-for-granted order of things that structures how a person spends time, money and attention, and 'mastery of life,' the active effort to keep that order coherent and to restore it when disrupted. Both are shaped by habitus and social class, which mold a person's source preferences and problem-solving styles. ELIS thus situates everyday seeking within a socio-cultural and value framework rather than treating it as isolated, task-driven retrieval.
