Bertie Brookes and I shared a common view that, beyond the practical activities of information provision, there could be discerned a more general sci… - Brian Campbell Vickery

My first encounter with the concept of "information service" came with the reading of The Social Function of Science by Desmond Bernal, first published in 1939-a work that stimulated a whole generation of young scientists to think about the role of science in society, its organisation, its future. In it, he wrote that in every laboratory "there should be someone deputed to watch the whole of current literature for items which might be relevant to the work of the laboratory, and to be able to indicate without loss of time where such items are likely to be found." Such a person "would have to be chosen partly for his comprehensive scientific interests, which need to be much greater than those of the other laboratory workers, and partly for his inclination to systematic thinking." Already I felt that I might be suited to such a role.

”Information science” emerges (a) when conceptual explorations, not directed towards immediate practical or technical ends, begin to take place, and (b) they are seen to be concerned with a definable area of interest [that of facilitating the transmission of information between people].

The scope of a specialised documentary classification is usually designated by its title, the subject field that it professes to classify. It is no easy task to state what is meant by a subject field. In general it can be expressed as Thing-Activity. A definable group of things... is selected, and from the many relations in which they subsist a certain number are selected as relevant.
