The first section establishes a working definition of library science and outlines the existing publications patterns of library science information. The existing system of bibliographic organization is examined in detail and services provided in the U.S.S.R. are described as an example of a systematic attempt at world coverage. In late 1967, efforts were so diverse that no one service (or group of related services) provided reliable coverage of current information. The existing literature on the attitudes of the user of library science information is reviewed, together with literature on more general aspects concerning the publications covering the field. The second section which deals with steps toward a model scheme is mainly concerned with the needs of the English language bloc. The establishment of an International Study Group is suggested to study library science information problems with the three main tasks of: 1) a survey of information needs, producing a user profile; 2) a survey of information patterns, producing an information profile and 3) a comparison of the two profiles leading to the construction of a master scheme of information services to cover both primary and secondary services.
