Assuming that workplace significantly affects information seeking and information management patterns,this study explores accessibility and management of information sources among a group of research engineers.The study explores how these engineers, who belong to the R&D entity of a major energy group,require, search and manage information sources in given professional contexts. Furthermore, it strives toidentify the contextual factors that shape information practices. This empirical study is based on a qualitativeapproach: following exploratory inquiries, semi-structured interviews and observations were conducted witha small group of actors in their proper workplace.

The study provides an analytic cartography of the various components of the organizationaland informational environments whereby the activities and tasks of the above mentioned actors takeplace. A wide range of practices has been identified via interviews but also through the activities and workrhythms observed. An appreciative framework has been developed to analyze the practices of access to informationproduced and used in professional contexts; it underlines the contextual factors that may becomedriving dimensions to support an innovative perspective on information management structures. The studyattempts to provide an innovative approach for the analysis of information practices in contexts, orientedtoward the design of a facetted and collaborative information management system.
