However, research libraries have responsibilities for future generations cost considerations of short‐
term use are not adequate to ensure research level collections, whether in digital or analog formats.
According to a report on collections and access issued by ARL, “developments in digital technology, the
introduction of the Web and the Internet, and new methods of creating, sharing, and using knowledge
have changed dramatically the traditionally understood definitions of library collections and access
services. Building collections and creating access to them are no longer achieved just within the walls of
the library. Broadly defined, collections and access responsibilities are no longer distinct spheres within
research libraries. Collections and access responsibilities are inextricably linked—with each other, with
other functions in the parent institutions, and, indeed, with other institutions. This interdependent and
fluid environment presents challenges but, more importantly, it presents opportunities for librarians to
take leadership roles in creating new information services in support of research and learning and
thereby diffuse the library throughout the institution.”23
