Presents the background and rationale for a description of information systems which places typical information retrieval and other types of systems in context with one another. Examples are drawn from various types of information systems, and a typology is derived for identifying useful combinations of data type, retrieval mechanism, and…

The primary scope of this publication is to contribute to the promotion of research in the general area of manpower and employment by surveying the supply of statistical data with a view to stimulating and facilitating their analytical use. Since the mass of relevant manpower data in this country is enormous, it was decided to approach the problem…
