Some changes occurred in the nineties. In 1995, three directors had background in humanities, while 14 held medical degrees. The transition began in the mid-eighties, when college librarians were being asked to deliver more quality services for the faculty, libraries were beginning computerization, and many senior directors were to retire. The selection of successful candidates became crucial for the development of medical librarianship. Obvious achievements have been made in many influential libraries since the new directors came.
Disadvantages always coexist with their counterparts.
Professors and administrative heads are usually reluctant to accept the new position with which they were unfamiliar, or they only promise to stay at the library for several years before their retirement. Over the past decade, three changes in director at an individual library happened in nearly half those institutions mentioned above. The tenure of office for these directors tended to be too short. Instability of the leadership affects the morale unfavourably and retards the advances of the library. Some experienced successors selected from within have demonstrated successful performance.
