    Abstract
    The human natural ability to store and process images and speech provides clues for improving access to online information. The principles underpinning the maps people use in their minds can be applied to maps that can be presented at the user interface to online systems. Traditional classification organizes information into structured hierarchies and simplifies the search problem, but has serious limitations. Discusses the prospects for improving access to online information through the application of dynamic faceted classification. Presents a glimpse into the navigation of n-dimensional information space for future library OPACs using a modified DDC

    Abstract
    Presents a pilot study for an Internordic project to monitor the use of online catalogues in the Nordic technological university libraries. Focuses on the use of classification in subject searching, how the UDC is used and the extent of its use. Studies user interaction with the OPACs and improvements to information retrieval in the catalogues using the transaction log method to gather data. The pilot study examnines the TENTTU Books database which is the online union catalogue of the Helsinki Univ. of Technology Library, a multilingual database with true information retrieval. The Internordic study itself will make comparisons between the TENTTU system and the new Virginia Tech Library System. Discusses the users monitored, method of analysis, subject searching in the database, results and how the UDC codes were used. Compares this to other studies conducted in Finland and evaluates the project

    Abstract
    Online displays of bibliographic records in call number order can serve various functions. A literature search showed no papers or books discussing this topic directly. Various displays from online catalogues available via the Internet were examined, as were displays sent to the author by colleagues. A number of the displays were uninformative to the extent that the identification of works associated with call numbers was difficult or impossible without follow-up searching of the individual bibliographic records. Other displays provided information where further searching of the database would not be required for most purposes. Displays noted ranged from displays with call numbers alone, with no bibliographic information, to records including main entry, title, statement of responsibility, place, publisher, and date. Suggestions of useful data elements to be included in displays of bibliographic records in call number order are made for the following functions: shelflisting, cataloguing, catalogue maintenance, reference, public searches, acquisition and collection development, and inventory control. Recommendations are made that the following data elements should be present in call number displays: entire call number as a sequencing element; main entry; entire title proper, and the date. Concern is expressed that the call number filing arrangement be that followed in traditional shelflists, and a suggestion is made that possible consensus on the placement of the data elements within a display be considered in the future

    Abstract
    The physical organisation of items on library shelves using any classification scheme is inevitable a compromise. The best efforts to achieve an arrangement that is helpful to users will be thwarted by the multifaceted nature of these items and the specific needs of the user and the library. Items on a particular subject will be scattered throughout the library building(s) across disciplines, by physical form, by frequency of use and whether and for how long they may be borrowed. Even thought he rich information content of multifaceted items may be represented in the notation, the items required by a user will be scattered across library shelves when the item is placed in a single relative location. This paper explores these issues uisng examples from a University Library classified using the DDC. The electronic context of the library OPAC can transcend the constraints imposed by the predominantly physical nature of library collections, yet the current use of classification schemes in on-line systems retains many of these limitations. Examples of such systems applying DDC on the WWW are discussed and compared with a system that seeks to use DDC in what is called view-based searching. The interface and the resulting browsing and searching capability of a view-based OPAC are described. Ways in which subject access to library collections can be improved and disciplinary scatter resolved by assigning multiple class number to items and exploiting the rich Dewey structure in a faceted form are discussed. It is suggested that the informative power of visual classificatory structures at the search interface will be beneficial to the broader learning experience of the user. The paper concludes that the application of classification schemes in electronic interfaces should not be bound by the the physical constraints that no longer apply in an electronic context but be exploited to provide a complete, flexible and individual interface as determined by the needs of each user
