James L. Mullins et al. have self-archived the Library Publishing Services: Strategies for Success: Final Research Report in e-Pubs,. In 2011, a more detailed preliminary version of the report was released, and readers may want to consult that as well.
Here's an excerpt:
This report briefly presents the findings and recommendations of the "Library Publishing Services: Strategies for Success" project which investigated the extent to which publishing has now become a core activity of North American academic libraries and suggested ways in which further capacity could be built. The research described (consisting of a survey, some case studies, three workshops, and a set of further reading recommendations) was mainly conducted between October 1, 2010, and September 30, 2011. It was supported by a grant from the Institute for Museum and Libraries Studies, made to Purdue University Libraries in collaboration with the Libraries of the Georgia Institute of Technology and the J. Willard Marriott Library at the University of Utah.
