"I suspect that teaching the history of our subject is less frequent in our institutions than it was. We are getting short-sighted both in looking forward and in looking backward, to our detriment."

"Facet analysis results in more varied, multidimensional relationships, at least in theory, better reflecting the complexity of subject knowledge"

"Neither citation nor loan demand is an adequate measure of literature use by a large community. Each is only an indicator, illuminating some aspects of use but with its own inherent bias. The joint study of several indicators gives a more balanced picture.."

"Citation does not necessarily reflect current demand."

"[Vickery in his handbook of procedures for making , writes that organizing a field into facets] can be achieved only by a detailed examination of the literature of the field"

"Information retrieval is now an accepted part of the new discipline of information science and technology... I have concentrated on the field with which I am most familiar, the problems of bibliographic description and subject analysis."

"The crux of the retrieval problem is that selecting documents to read grows ever more difficult, and new techniques are continually needed."

"User needs determine what functions should be provided, and different functions require different structures."

"Information science is concerned with every aspect of the chain of information transfer activities, but the heart of its interest is information search."

"Despite the fact that our profession constantly urges others to “consult the literature”, I do not think we are distinguished nowadays by knowledge of our heritage."

"I would pinpoint 1958 as a special time in my career. I had for some years been working with the Classification Research Group in London, and in 1957 we had held a small but successful conference to which Jesse Shera, Gene Garfield and others had come from the USA. In 1958 I published my first book, Classification and Indexing in Science, and attended the International Conference on Scientific Information in Washington. This was my first visit to the USA - I flew in a US Army transport plane with . The Conference papers opened up all kinds of new information vistas - in many ways setting the agenda for the ensuing development of the field. I met many interesting people - some who stand out in the memory are Peter Luhn, , John O'Connor and Desmond Bernal. The experience of attending the conference, and of other visits I paid at that time, led to the writing of my second book, On Retrieval System Theory..."

"Throughout life, all people are engaged in activities – practical or mental – trying to solve problems, activities that themselves give rise to problems. To solve these problems, people need knowledge. They can acquire this personal knowledge in two main ways. First, they can interrogate the world – natural and social – by means of closer observation, deeper analysis, controlled experiment, all forms of cognitive interaction. Second, they can enrich their personal knowledge by communicative interaction with the stock of public knowledge that mankind has built up over the millenia, thus acquiring what we may call information. The activities in which people engage also produce two other kinds of knowledge: that embodied in people (skills) and that embodied in their artefacts."

"John Desmond Bernal (1901-1971) was undoubtedly the most important of the "Western" scientists who, during the twentieth century, accepted the Marxist view of social development. He did more than "accept" it: he tried to sketch the whole history of science from a Marxist viewpoint; he wrote a number of articles explicitly expounding his view of the relation of Marxism to science; and from his student days he played an active role in Communist politics. He has been criticised: during his lifetime, for too readily accepting official Soviet policy, whether relating to society or to science; since his death, for having been too ready to hope that his vision of the use of science for human ends could be implemented by capitalist societies; and at all times, for an allegedly simplistic faith in science as the salvation of mankind."

"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."

"What is now called ‘knowledge organisation’ in this context has a long history. The simplest forms of a knowledge organisation system (KOS) are, after all, the contents list and the index of a textbook. The knowledge is in the text; the KOS is a supplementary tool that helps the reader to find his way around the text. But as such finding aids have become more complex, and taken on wider functions, they have acquired grander names, such as retrieval languages, taxonomies, categorisations, lexicons, thesauri, or ontologies. They are now seen as schemes that organize, manage, and retrieve information."

"I met Ranga on several occasions. He was a fascinating personality, highly organised, a tireless worker, a fierce enthusiast, a charming man. Speaking of his passion for work, he told me once how his young son had stuck a notice on his study door: “Librarianship is unfair to families”... It really was a privilege to have known him."

"Interaction is the mode of life of living organisms. Each must feed on its environment, ingesting chemicals or other organisms. This is something more than "interaction", it is activity directed towards the environment. Since the organism must be selective in what it ingests, it needs to discriminate among the entities in its environment. From very primitive forms of discrimination, the sensory mechanisms of organisms have evolved into the senses of man, interpreted by an internal cognitive apparatus, memories of past experiences, and an ability to take rational decisions. By "rational" I mean activity that achieves intended results because it is based on a reliable understanding of the nature of the environment. In interacting with each other to carry out tasks jointly, men have further developed language, leading to a shared understanding of the environment. This shared understanding is knowledge."

"The preface to the first edition of this book... shows that in 1958 the classification ideas in it were felt to controversial, needing to be championed. A few years before, the had issued a memorandum proclaiming "the need for a faceted classification as the basis of all methods of information retrieval'. As part-author of this memorandum, I must now judge the claim to have been too bold, even brash."

"The classification of subject matter may be carried out for all sort of special purposes - to arrange books on shelves, to group inventions in patents, to classify the raw materials, intermediates and products of importance to a particular manufacturer, and so on. All such arrangements have their particular uses and their particular problems."

"Classification in its simplest terms, means putting together things or ideas that are alike, and keeping separate those that are different."

"The basic rules of classification are - Each characteristic of division must produce at least two classes - Only one principle of division must be used at a time, to produce mutually exclusive classes. - The species of any genius must be completely exhaustive of their parent class."

"In science there are uses many classifications of entities - plants, animals, rocks, soils, stars, diseases, occupations, and so on. In these taxonomies a classification must display genetic relations - for example, an evolutionary family tree of animal species - but its prime purpose is to aid in the identification of entities... Classification enables us to select, from the whole universe of known entities, the one that best matches one newly encountered."

"Scientific information is faced with the following problem. On the one hand, we have the world’s literature of science and technology, past and present, in many languages; on the other, and enquirer with a question. How to select, from a vast mass of words, the few that are the most closely relevant to an enquiry? It is this selection process that makes use of classification."

"The most important characteristic of documentary classification is that it is concerned with subjects, not just entities of taxonomic classification. What is the nature of the specific subjects - the themes on which books, parts of books, articles or parts of articles are written? A study of book titles alone would suggest that literary subjects have simple names like 'War, Religion', 'Boats', 'Musica; pitch', 'Colour', 'Acridines', 'Wild flowers', and so on. But the study of articles on the documentation level reveals that such titles are simple in appearance only. Such a literary subject is in reality a complex aggregate of specific subjects, eahc which is the main theme discussed from one particular aspect."

"In scientific information, then, we find that subjects - the themes and topics on which books and articles are written - cluster into fields, each of which can be analysed into its characteristic set of facets of terms."

"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."

"Classification in documentation is a tool for selection. It is essentially a 'finding system' for subject items... It is an artificial language, designed as a tool to aid in the selection of information from a store in response to search questions. The classification serves to standardise subject description, so that the description of a subject used by indexer and inquirer are more likely to coincide, thus maximising the probability of finding all items relevant to an inquiry."

"The structure if a fully developed classification can be technically described in the following way:"

"History presents a series of cultural epochs. Each is a span of years within which knowledge presents a more or less unified structure which can be expressed in a classification, but each new epoch requires a new classification."

"Throughout the nineteenth century, apart from the division in theoretical sciences and arts, classifiers attempted to divide the sciences into two groups. Already they had before them the examples of Francis Bacon (speculative and descriptive) and Hobbes (quantitative and qualitative). For Coleridge, the sciences were either pure (Grammar, Logic, Rhetoric, Mathematics, Metaphysics) or mixed. Arthur Schopenhauer’s similar groups were called pure and empirical, Wilhelm Wundt in 1887 called them formal and empirical, Globot mathematical and theoretical, and the St. Louis Congress of Arts and Sciences (1904) normative and physical. made similar division of the sciences into abstract and concrete"

"Four basic operations in the effective use of graphic records (documents), to store information and make it available, have been listed by Hyslop: A, recording information in documents; B, storing recorded information—documentary items; C, identifying items containing information relevant to a given problem, situation, or subject; D, providing the identified items from storage. Information storage and retrieval in the wide sense covers all these operations. In the narrow sense used in this paper, information retrieval means only C, identifying documentary items by subject."

"An information retrieval system is therefore defined here as any device which aids access to documents specified by subject, and the operations associated with it. The documents can be books, journals, reports, atlases, or other records of thought, or any parts of such records—articles, chapters, sections, tables, diagrams, or even particular words. The retrieval devices can range from a bare list of contents to a large digital computer and its accessories. The operations can range from simple visual scanning to the most detailed programming."

"A retrieval system can be studied at three levels:"

"# The way in which units of information, and relevant relations between them, are defined in the system. This is the semantic level of subject analysis."

"# The general structural features of the system considered as a network of units of information linked to each other and to documentary items. This may be called structural analysis."

"# The physical mechanisms (hardware) in which the structure is embodied."

"Four years ago, when the first edition of this book was written, information retrieval was beginning to crystallize out as a unified discipline. The process has gone further today. Several other books... have also offered a general survey, although each has contributed its own special emphasis. Many conferences on the subject have been held, and a constant stream of new articles has appeared, both in documentation journals and in those in the data processing field. Information retrieval is now recognized as a discipline, and further advances in theory are being made, What I described in the first edition as the key operation in retrieval — the subject description of documents — is being explored theoretically and experimentally, although we are still a long way from reducing this operation to rule (Chapter 3). There has been less new work on the design of descriptor languages, although ideas on the display of descriptor relations through thesauri and 'semantic maps' have been developed (Chapter 4). Access to files has been examined, particularly by those experienced in data processing."

"There is as yet no unified theory of retrieval systems, and a good deal of retrieval practice is still an empirical art, unsullied by theory."

"Systems transfer or transform materials, energy or information - and usually all three. An information system is one whose prime function is to transfer or transform information: the telephone system is an obvious example. This book concentrates on certain types of information system: those concerned with the transfer of information between specialists, mainly with reference to their work, and mainly based on documents. The focus is thus on specialised documentary information systems."

"The areas traditionally concerned with such systems are: publishing in all its ramification, librarianship, bibliography, documentation, record management, archives and the like. Systematic study of the activities in all these areas has lead to increased recognition of their common features. They are all concerned with information systems, and their study may include in the wider field of 'information science and technology' (as the Americans put it) or 'informatics' (as Soviet writers would have it)."

"An information system is an organisation of people, materials and machines that serves to facilitate the transfer of information from one person to another. Its function is social: to aid human communication. If we take this to mean all reception of signals by the human senses (sight, sound, small, touch, taste,...)- then communication is an incessant and essential accompaniment of all human activity. If we restrict the meaning of signals to flowing between people, much of the daily life of most of us is occupied by such interpersonal acts."

"We communicate with each other to inform, to instruct, to persuade, to amuse, to annoy. Informing and instructing aim to alter the receiver's concepts, whereas persuading, amusing or annoying aim to change his preferences or feelings. In a work situation people do make jokes and enemies, and use the arts of persuasion, but much of their communication has an informal or instructional aspect."

"”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]."

"In its whole sweep, therefore, information work includes: science, that helps us to understand our problems; technology, that helps us to solve them; and the art of participating in each delicate interpersonal communication into which we are invited. The fusion of these three aspects of the craft creates a “triple glow” of optimal service."

"The area of scientific interest is... the study of the objectives, functions, structure, properties, behaviour, performance and effects of informative communication processes and information systems. To this study the name "information science" can legitimately be attached."

"… it is most important – particularly in an immature field like information science - to accept that all modes of study and all analytical methods can make useful contributions, and not to denigrate [qualitative] models as “just description”"

"The field of study [of information science] is so wide and varied; research is necessarily restricted to accessible areas; it often (and rightly) has the practical aim of providing guidance in a specific situation, rather than searching for generalisations; the isolation of variables for investigation is often so difficult; rarely can confirmatory experiments be undertaken."

"Documentation is a practice concerned with all the processes involved in transferring documents from sources to users."

"In the past, documentation has frequently been compared with librarianship, with some argument as to which comprehends the other. The field is more helpfully characterised if we take its scope to be all forms of document (i.e. any physical carrier of symbolic messages) and all aspects of their handling, from production to delivery. The document system then becomes very much wider than conventional librarianship – it includes publication and printing, distribution, some forms of telecommunication, analysis, storage, retrieval and delivery to the user."

"The representation of knowledge in symbolic form is a matter that has pre-occupied the world of documentation since its origin. The problem is now relevant in many situations other than documents and indexes. The structure of records and files in databases: data structures in computer programming; the syntactic and semantic structure of natural language; knowledge representation in artificial intelligence; models of human memory: in all these fields it is necessary to decide how knowledge may be represented so that the representations may be manipulated."
