# The physical mechanisms (hardware) in which the structure is embodied. - Brian Campbell Vickery

I am always surprised that the information profession, so quick to sing the virtues of literature search for its customers, pays so little attention to its own history. I have been told: “our problems are different from those of the past”. It is not so the problems are often the same, only the technical means available for solution may be new. The thinking and experience of the past can often shed light on the present.

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.

Mass communications analysts concentrate on “who sends what information, for what purposes, through what channels, to which people, with what effect”. The information profession is more interested in “who seeks what information, for what purposes, through what channels, from which people and sources, with what success”.
