OCLC Programs and Research has published Beyond the Silos of the LAMs: Collaboration Among Libraries, Archives and Museums.
Here's an excerpt:
The project that forms the basis of this report began in 2007, when RLG Programs initiated work on the program, Library, Archive and Museum Collaboration. The goal of the program was threefold: to explore the nature of library, archive and museum (LAM) collaborations, to help LAMs collaborate on common services and thus yield greater productivity within their institutions, and to assist them in creating research environments better aligned with user expectations—or, to reference this report’s title, to move beyond the often-mentioned silos of LAM resources which divide content into piecemeal offerings.
At the heart of the program was a series of workshops designed to be both exploratory and outcome-oriented. Workshop participants were asked to identify motivations and obstacles in the collaborative process and plan new collaborative projects and programs that addressed needs at their own institutions.
Five RLG Programs partner sites were selected to participate in the workshops: the University of Edinburgh, Princeton University, the Smithsonian Institution, the Victoria and Albert Museum, and Yale University.
