ARL has released the Changing Role of Senior Administrators, SPEC Kit 331.
Here's an excerpt from the press release:
The Association of Research Libraries (ARL) has published Changing Role of Senior Administrators, SPEC Kit 331, which focuses on the professional, administrative, and management positions that report directly to the library director (or, in some ARL member libraries, the position that serves as the representative to the Association), positions that have not been examined by a SPEC survey since 1984. This SPEC Kit explores the responsibilities of these positions, and the skills, qualifications, and competencies necessary for these administrators to successfully lead a transforming 21st-century research library. The publication looks at whether and how position requirements have changed in the past five years, whether the number of direct reports has changed, whether these administrators have assumed new areas of organizational responsibility, and how they acquire the new skills to fulfill those responsibilities.
