The work of the information officer [should be] regarded as the natural dynamic extension of that of the librarian. - Douglas John Foskett

The 1950s to early 1960s saw the publication of three major works on indexing, which between them span the retrieval problems of the whole spectrum of knowledge... The first was Vickery’s Classification and indexing in science (1958), followed by Foskett’s Classification and indexing in the social sciences (1963) and finally Langridge’s Classification and indexing in the humanities (1976). These three works, though designed principally as textbooks, expound many universal principles as well as highlighting the specific problems that the various groups of disciplines present and the solutions that have been adopted.

In 1948, it was agreed that a study of classification should be made, and a committee of scientists was appointed under the leadership of Professor. J. D. Bernal.

One of the most prominent figures in contemporary British library and information science, Douglas John Foskett made many, varied, and important contributions to library and information science. Classification was always one of Foskett's major interests, and in 1952 he was one of the founders of the Classification Research Group in Britain. But he proved equally influential in the fields of comparative librarianship and library education and in the development of the Library Association (LA).
