Abstract

Reports experimental results concerning user interaction with document organisation, user-librarian negotiation and the librarian's search process in public libraries. The focus of the investigations is on the cognitive aspects of information retrieval. Discusses the cognitive viewpoint on which the research is based, outlining applicable findings and theories within the fields of cognitive science and cognitive psychology. It is shown how the user's knowledge structure cope with the structures of the system. User needs seem often to be presented as a label which may create ambiguity problems. Functions of open and closed questions are investigated and certain behaviouristic factors discussed. Librarians prefer search activity before consideration of the presented problem. Without a user present the librarian's information retrieval process is determined by 3 search attitudes involving motives and expectations as to search routines and possibilities. Conceptual knowledge, previous search and working domain play important roles. The attitudes have consequences for the objectives concerning use of routines and for the use of search concepts
