Abstract: Over the past five years, libraries have begun to expand their role in the scholarly publishing value chain by offering a greater range of pre-publication and editorial support services. Given the rapid evolution of these services, there is a clear community need for practical guidance concerning the challenges and opportunities facing library-based publishing programs.Recognizing that library publishing services represent one part of a complex ecology of scholarly communication, Purdue University Libraries, in collaboration with the Libraries of Georgia Institute of Technology and the University of Utah, secured an IMLS National Leadership Grant under the title “Library Publishing Services: Strategies for Success.” The project, conducted between October 2010 and September 2011, seeks to advance the professionalism of library-based publishing by identifying successful library publishing strategies and services, highlighting best practices, and recommending priorities for building capacity.The project has four components: 1) a survey of librarians designed to provide an overview of current practice for library publishing programs (led by consultant October Ivins); 2) a report presenting best practice case studies of the publishing programs at the partner institutions (written by consultant Raym Crow); 3) a series of workshops held at each participating institution to present and discuss the findings of the survey and case studies; and 4) a review of the existing literature on library publishing services. The results of these research threads are pulled together in this project white paper.
