During the past decade, the scope of information science has been evolving into a broader but better defined area of specialization. In this paper several of the definitions of information science which have been suggested by various professional groups are discussed. The educational objectives of information science are identified, and the curricula necessary to achieve these objectives are outlined. The paper discusses the changing nature of the library's role in information science and the impact of computers on the field of information science in general. A list of references is appended. (JY)
