Efforts to improve efficiency, cut red tape, speed operations and provide better service to the user are shown by each reporting department. The Processing Department, for example, adopted a new system of priorities in an effort to get books to the shelves faster and cataloging information to subscribing libraries more promptly. The Reference Department established new procedures for coordinating automation activities and for disseminating information on these activities, and conducted a management survey of the National Union Catalog Reference Service. The Congressional Research Service subjected many of its operations to a critical overview. The Administrative Department concentrated on greater flexibility in management, establishment of a comprehensive management planning program, and better means of communication. The Law Library revised its acquisition and retention policies, intensified its processing activities, and planned an extensive series of publications to aid legal research. The Copyright Office felt the need to utilize time and resources in the most effective manner. The 14 appendices show, in tabular form, the growth of the Library of Congress collections and many of its operations. The index is a merged listing by subject and author in alphabetical order.
