- Abstract
- An information retrieval system for a cataloguing database through the WWW is developed, and experimentally served to Japan MARC and ULIS (Univeristy of Library and Information Science) OPAC data. Since Japanese words are not separated by obvious delimiters, ensuring the same segmentation between the query and the database is a problem. The present system solves the problem by using the multiple hash screening technique for processing both book titles and query strings, based on the same dictionary and using similar algorithms. Database management is handled by ADABAS, reducing management chores and and response time. The effectiveness of the multiple hash screening technique for a Japanese text based information system is examined, and the limitation of the Web's hypertext environment for a bibliographic information retrieval service is discussed

- Abstract
- Reviews a series of studies conducted by C.C, Kuhlthau who investigated users' information seeking behaviour in libraries over a 10 year period. In her study she constructed and Information Search Process (ISP) Model which represents aspects of user activities as a whole including feelings, thoughts and actions or behaviour. Argues that, while the ISP model sheds new light on user studies, it has problems in the following areas: problem solving processes; the understanding of 'feelings'; and the method of investigating users' information seeking behaviour. Recommends that the ISP model be reconstructed from different perspectives and verified in areas other than libraries. This may lead to the development of a new model of information seeking

- Abstract
- The terms search strategy, search tactics, and moves are used to refer to interaction between an information retrieval system and the user. Examines papers using search strategy, search tactics, moves and analyzes the meaning of these terms. Suggests the need to use strategy and moves in information seeking studies

- Abstract
- Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth

- Abstract
- The Nippon Decimal Classification (NDC) system, extensively used in Japanese libraries, was devised in 1929. It is difficult to use NDC to classify world literature, such as fiction in English by non American, non British writers. This is not necessarily straightforward in other classification schemes but a survey of 40 Japanese university libraries, of which 24 responded, showed remarkable inconsistencies in the treatment of 22 world literature authors. NDC clearly needs updating to deal with this problem

- Abstract
- 2 concepts of facets have been used in studies of classification systems: one for systems which take hierarchical structure and the other for systems which take multidimensional structure. Both correspond to 'principles of division'. The concepts of facets in multidimensional structure systems is used for addressing a subject from many aspects so should equate to the broadest principle of division in order to grasp a multiplicity of aspects. The concept of facets used in hierarchical systems addresses only the significance of a coherent set of items. This concept is not distinguished from the principle of division and there is no purpose in introducing a concept of facets into hierarchical systems in addition to the principle of division
