The Association of Research Libraries has released "Issue Brief: 21st-Century Collections: Calibration of Investment and Collaborative Action."
Here's an excerpt from the announcement:
Carton Rogers, Vice Provost and Director of Libraries at the University of Pennsylvania, chairs the ARL Transforming Research Libraries Steering Committee, which originally requested the issue brief. According to Rogers, this paper provides directors with an excellent overview of emerging and horizon issues and the challenges of building 21st-century collections. "The paper's emphasis on networked resources, teamwork, and cross-institutional collaboration underscores the need for new roles and new competencies for our workforce, which is currently a key focus of the committee's agenda. We encourage discussions of the shared future projected in the report, its implications for library staff, and for the ongoing support of research, teaching, and learning on our campuses."
