The contents of this publication include the background papers used at the Institute on Discovery Management for Supervisors of Library Branches Serving the Underprivileged and Emerging Community held July 26-August 13, 1971 at the Graduate School of Library and Information Science, University of Pittsburgh. It is the purpose of this publication to assert that a "bold new approach" to the evaluation of library service is needed in order to exert leadership in the patterns of citizens involvement and local control. The core of the problem includes these imperatives: to integrate library service with the community; to focus attention upon the imperatives of a right to read and new careers; to make the full range of information and communicative help which the community has to offer readily available to persons in need; to increase the likelihood that concerns can be identified and help provided early enough to do some good; to strengthen the service program of the community library for the prevention of information dislocation. The citizens themselves should ultimately be involved in determining the kind of information programs they get. Without a situation-producing theory of communications, it is unlikely that librarians will ever produce the strategies for community leadership. (Author)
