This conference was held to bring librarians and users from academic, public, school, and special libraries together to discuss how resource sharing among all types of libraries, for the benefit of all types of users, might be enhanced through formal multitype networking. A conference workbook was provided for participants to read ahead of time, and much of the work accomplished at the conference was done through interaction in small and large group sessions. Several resource persons and an on-site study collection were also provided, as well as two major speakers. These proceedings comprise: (1) the keynote address, "Legislation to Provide Something to Share" (Major R. Owens; (2) summaries of daily activities; (3) the conference address, "Benefits of Multitype Cooperation" (Hugh C. Atkinson); (4) an agenda for action; and (5) a response by Gary E. Strong. Appendices include: a full list of conference attendees; the conference workbook containing commissioned essays as well as the results of commissioned research on multitype networking; a bibliography of the on-site study collection; and brief biographies of conference resource people.
