    Abstract
    This piece of research traces the evolution of guidelines and principles for the construction of information retrieval thesauri from 1959 to 1993. We conclude that the majority of the basic problems of thesaurus construction has already been identified and solved by 1967 and that Eugene Wall, more than any other individual, has profoundly influenced the entire development in this area

    Abstract
    The 2nd Int. Study Conf. on Classification Research was held in Elsinore, Denmark on 14-18.9.1964. That conference is revisited and compared with the present ISKO '94 conference on Knowledge Organization and Quality Management to show how much progress has been made, how many old problems still await solutions, and why the fields of work called Classification Research and Knowledge Management have much in common

    Abstract
    Vannevar Bush's famous article, 'As we may think' (Atlantic monthly 176(1945) S.101-108) described an imaginary information retrieval machine, the Memex. The Memex is usually viewed, unhistorically, in relation to subsequent developments using digital computers. This study reconstructs the little-known background of information retrieval in and before 1939 when 'As we may think' was originally written. The Memex was based on Bush's work during 1938-40 in developing an improved photoelectric microfilm selector, an electronic retrieval technology pioneered by Emanuel Goldberg of Zeiss, Ikon Dresden, in the 1920s. Visionary statements by Paul Otlet (1934) and Walter Schürmeyer (1935) and the development of electronic document retrieval technology before Bush are examined

    Abstract
    This paper attempts to summarize the rich and interesting history of cataloging in Medieval monastic libraries, when the production of books was in its infancy. It discusses some of these early practices when books were few in number and very valuable to the community. In the beginning, catalogs were mostly inventory lists of treasures, not used for research direction. Only the librarian or armarius was consulted for research direction. Complicating these practices was the fact that several "books" were often bound together in the same binding which would have hindered subject cataoging. As books' value evolved toward their subject matter rather than their value as physical objects, and the catalog grew from an inventory list for the librarian toward a guide for patrons, and the rudimentary inventory practices grew toward the modern research direction-oriented cataloging methods, the medieval catalog approached the modern catalog in purpose and content.

    Abstract
    In 1964 Swanson published an article 'Dialogues with a catalog', in which he presented a personal prescription for what a library catalog should look like at some future date. He was in many ways remarkably visionary; some of the features he recommended have still not been implemented, although writers are again referring to their desirability. Despite its visionary qualities, Swanson's article seems to have been quite forgotten. At least, it is rarely cited. This article will trace the development of OPACs from the time they were first introduced into libraries and compare what has occured with Swanson's recommendations. It is remarkable that an article written thirty years ago could still offer a suitable framework within which to review virtually the totality of OPAC developments. The lesson that emerges most clearly from this is that the library profession should prescribe performance goals for tools and services that are not constrained by existing technologies. We must first establish requirements and seek the solutions later

    Abstract
    Provides a history of the development of coordinate indexing and searching. In the 1930s scientists began to use edge notched punched cards for searching. The Batten system was invented in 1944. Following the World War 2 these systems underwent major enhancements: Calvin Mooers built up the punched card system with his Zatocoding, and Mortimer Taube enlarged the peek-a-boo system with his Uniterm development. 2 computerizations' of Taube's Uniterm system led to the present day world of information retrieval

    Abstract
    This article desribes the evolvement of computerized information storage and retrieval, from its beginnings in the theoretical works on logic by George Boole in the mid-nineteenth century, to the application of Boole's logic to switching circuits by Claude Shannon in the late 1930s, and the development of coordinate indexing by Mortimer Taube in the late 1940s and early 1950s. Thus, electronic storage and retrieval of information, as we know it today, was the result of two major achievements: the advancement of computer technology initiated to a large extend by the work of Shannon, and the development of coordinate indexing and retrieval by the work of Taube. Both these achievements are based on and are the application of the theoretical works of George Boole

    Abstract
    The work of the Belgian internationalist and documentalist, Paul Otlet (1868-1944), and his colleagues in Brussles, forms an important and neglected part of the history of information science. They developed a complex of organizations that are similar in important respects functionally to contemporary hypertext/hypermedia systems. These organizations effectively provided for the integration on bibliographic, image and textual databases. Chunks of text on cards or separate sheets were created according to 'the monographic principle' and their physical organization managed by the UDC, created by the Belgians from Melvil Dewey's DDC. This article discusses Otlet's concept of the Office of Documentation and, as examples of an approach to actual hypertext systems, several special Offices of Documentation set up in the International Office of Bibliography. In his Traité de Documentation of 1934, one of the first systematic treatises on what today we would call information science, Otlet speculated imaginatively about telecommunications, text-voice conversion, and what is needed in computer workstations, though of course he does not use this terminology. By assessing how the intellectual paradigm of 19th century positivism shaped Otlet's thinking, this study suggests how, despite its apparent contemporaneity, what he proposed was in fact conceptually different from the hypertext systems that have been developed or speculated about today. Such as analysis paradoxically also suggests the irony that a 'deconstructionist' reading of accounts of theses systems might find embedded in them the postivist approach to knowledge that the system designers would seem on the face of it explicitely to have repudiated

    Abstract
    Mobilising the information stored in documents to advance learning and social well-being provides information science with a fundamental social objective. It also presents it with a characteristic set of technical and professional problems. Until recently, information storage and retrieval systems, of which the library is one of the oldest and most important examples, have not provided a direct solutuion to the problem of providing access to needed information. Instead they have attempted to identify and provide physical access to written or printed documents that might contain information that is needed or might be useful. Perhaps creating systems to substitute what documents may be about for what documents contain is a process of realistic simplfication in the face of overwhleming technical and 'epistemological' problems. But it is speculative approaches to overcoming these problems that are the subject of this paper
