The December 1985 program session of the Library of Congress Network Advisory Committee (NAC) focused on determining the effectiveness of networking, identifying a common vision or goal, and developing a strategy to accomplish that goal. The program session included remarks on the role of the regional networks in national networking by Louella V. Wetherbee; a consideration of RLG (Research Libraries Group) in a nationwide network by Richard F. McCoy; a discussion of state libraries in national networking by James A. Nelson; presentations by private sector representatives and local systems representatives; and an overview and comments by Ronald F. Miller. The following papers, included in their entirety, were also presented: (1) "A Common Vision--Networking for Networkers and Librarians" (JoAn S. Segal); (2) "The Nationwide Network and OCLC--A Vision and a Role" (Rowland C. W. Brown); (3) "National Libraries' Vision of the Nationwide Network and Their Role in That Network" (Henriette D. Avram, Lois Ann Colaianni, and Joseph H. Howard); and (4) "A User's View of Networking" (Barbara D. Cooper). Also included are a list of conference attendees and summaries of NAC questionnaire responses, working group discussions, and the business session. A definition of networking, basic premises underlying library networking, questions for the NAC, and the conference agenda are appended; and a 12-item bibliography is provided. (KM)
