    Abstract
    In 1938 the Catalog Section of the American Library Association (ALA) mailed a questionnaire to approximately 1600 librarians, asking their opinions concerning various problems in cataloging and classification. Many changes have occurred since then, but there are problems cited in 1938 that are still with us in one form or another. The items listed in the questionnaire are discussed, and conclusions drawn as to their pertinence for today.

    Abstract
    E. Wyndham Hulme (1859-1954) proposed the concept of literary warrant as the basis of book classification and the definition of subject classes, wherein classes and names of classes would be derived from existing literature rather than a preconceived philosophical order of sciences, the predominant and favored type of classification system in Hulme's day. The methods of establishing classes by literary warrant are described and its relationship to what Hulme called "statistical bibliography" is explored.

    Abstract
    An exploratory study was conducted of elementary school children searching a full-text electronic encyclopedia on CD-ROM. 28 third and forth graders and 24 sixth graders conducted 2 assigned searches, one open-ended, the other one closed, after 2 demonstration sessions. Keystrokes captured by the computer and observer notes were used to examine user information-seeking strategies from a mental model perspective. Older searchers were more successful in finding required information, and took less time than younger searchers. No differences in total number of moves were found. Analysis of search patterns showed that novices used a heuristic, highly interactive search strategy. Searchers used sentence and phrase queries, indicating unique mental models for this search system. Most searchers accepted system defaults and used the AND connective in formulating queries. Transition matrix analysis showed that younger searchers generally favoured query refining moves and older searchers fovoured examining title and text moves. Suggestions for system designers were made and future research questions were identified

    Abstract
    One of the earliest works on the theory of classification appeared in a series of six chapters an the "Principles of Book Classification" published between October 1911 and May 1912 in the Library Association Record. In this publication, the author, E. Wyndham Hulme (1859-1954) whose career included twenty-five years as Librarian of the British Patent Office, set forth the fundamentals of classification as manifested in both the classed and the alphabetical catalogs. The work and the ideas contained therein have largely been forgotten. However, one phrase stands out and has been used frequently in the discussions of classification and indexing, particularly in reference to systems such as Library of Congress Classification, Dewey Decimal Classification, and Library of Congress Subject Headings. That phrase is "literary warrant"-meaning that the basis for classification is to be found in the actual published literature rather than abstract philosophical ideas or concepts in the universe of knowledge or the "order of nature and system of the sciences." To the extent that classification and indexing systems should be based upon existing literature rather than the universe of human knowledge, the concept of "literary warrant" defines systems used in library and information services, as distinguished from a purely philosophical classification. Library classification attempts to classify library materials-the records of knowledge-rather than knowledge itself; the establishment of a class or a heading for a subject is based an existing literature treating that subject. The following excerpt contains Hulme's definition of "literary warrant." Hulme first rejects the notion of using "the nature of the subject matter to be divided" as the basis for establishing headings, then he proceeds to propose the use of "literary warrant," that is, "an accurate survey and measurement of classes in literature," as the determinant.

    Abstract
    The argumetns of Pt.1-3 are applied to two main issues: (a) the separation of the physical and mental components of information phenomena, illustrated by a discussion of the aging of periodicals, (b) the role of the Bradford Law and ranking techniques as a means of exploiting all the information inherent in the raw data. The paper concludes with a brief discussion of a propsed new kind of data-base in which objective information is structured into objective knowledge

    Abstract
    In subject cataloging of audiovisual materials generic terms like 'documentary' or 'absolute film' facilitate the work of users and librarians. On the concrete level the study shows 4 ways to make a list of generic terms for the application in general libraries. The heuristic function of the study is to offer methods towards the solution of problems in the field of subject cataloguing of non-book materials. (1) The formal subject heading in library science corresponds to generic terms; Anglo-American and German rules for subject cataloging, however, provide no list that is directly applicable. (2) The terminology of institutions administering many audiovisual documents has been examined; general libraries have to find a common denominator with medium depth of classification and balanced representation of fiction and nonfiction terms. (3) From encyclopedic definitions of generic terms 8 dimensions have been extracted characterizing the terms in question individually. (4) The contribution of communication science has been discussed explaining a research project
