Access and Performance Measures in Research Libraries in the 1990’s
During the past 150 years, patterns of scholarship have changed dramatically, resulting in changes in the ways in which librarians and scholars alike view the role and mission of academic and research libraries. During the nineteenth century, the library’s mission was primarily to serve as a storehouse for books. 1 For the past twenty-five years, however, both librarians and scholars have viewed the library’s mission more broadly as facilitating the communication of social knowledge over time from one generation to the next. 2 Nevertheless, the statistical measures used to both describe and rank library activities and programs are still rooted in the past.
