David Ellis

David Ellis initial investigations of the behaviour of researchers in the physical and social sciences and engineers and research scientists through semi-structured interviews using a grounded theory approach, with a focus on describing the activities rather than a process produced six key activities within the information seeking process: Starting (activities that form the information search), Chaining (backwards or forwards - following references in initial information sources), Browsing (semi-directed search), Differentiating (filtering and selecting sources based on judgements of quality and relevance), Monitoring (keeping track of developments in an area) and Extracting (systematic extraction of material of interest from sources). Later studies by Ellis on focusing on academic researchers in other disciplines resulted in the addition of two more activities; Verifying (checking accuracy) and Ending (a final search, checking all material covered).
