    Abstract
    Betrachtet werden die drei Fragestellungen: (1) Welche Funktionen erfüllen Schlagwortketten im konventionellen Zettel- oder Listenkatalog? (2) Lassen sich diese Funktionen auf Online-Kataloge übertragen bzw. durch online-typische Funktionen ersetzen? (3) Welche Funktionen können SW-Ketten im Online-Katalog übernehmen?

    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
    Attempts to gauge whether syndetic structure, the cross reference system long regarded as an integral component of the controlled vocabulary which predominates as the indexing framework for online subject searching, still has a role to play in assisting end users in their information quests. To this end, examines a number of existing and proposed enhancements to OPACs by means of a literatur review. These include: Boolean and keyword searching; online browsing; artificial intelligence; classification clustering; and hypertext. Discusses Dervin's sensemaking theories and methodologies

    Abstract
    Introducess a new approach to display retrieved subject headings in subject searching designed to encourage users to browse bibliographic information. Emphasizes the importance of the exact display approach by showing how many user queries could be candidates for this approach, demonstrates an implementation of the exact-display approach in an experimental online catalogue. End user experiences gives opportunities to make recommendations for enhancing the original design of the exact display approach so that future implementations of this approach in operational online catalogues are responsive to the needs of online catalogue users

    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
    Browse searching of online catalogs and electronic indexes is a popular means of retrieving information, but some subject heading lists are so extensive that browsing them can be difficult and time-consuming. This resaerch tested one way of presenting a browse interface to reduce the amount of scanning of subject headings required. It found that a hierarchical presentation of headings reduced the amount of scanning required by more than 50% without any reduction in the effectiveness of the search. Better browsable displays of this sort can improve the efficiency of searching but appear not to alter effectivenenss

    Abstract
    Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

    Abstract
    As librarians increasingly try to use their online catalogues to do what used to be done with their card shelflists, they are realizing that some catalogue sedigners and vendors have not paid enough attention to online shelf order classification access. Compares the call number searching abilities of 8 prominent, mature library systems: VTLS, Inlex, Innovative Interfaces, Inc., Data Research Associates (DRA), Geac Advance, Dynix, SIRSI, and NOTIS. Using 5 criteria that are important to cataloguers, each system was tested and rated for its suitability as an online shelflist. *** Special note from the authors: "[We've] become aware of a new version of SIRSI's Unicorn library system-- version 7.0 that changes our rating of SIRSI in a major way. We had rated SIRSI Unicorn a "C" in the paper, but now we would rate version 7.0 an "A". This is indeed a major change. Fortunately, we identified version numbers for each system in the article: we had tested version 6.1 of SIRSI. Thus, version 7.0 of SIRSI Unicorn, available in early 1995, has improved to the point that it meets every criteria used in the article for suitability as an online shelflist. The authors have evaluated version 7.0 with an "A" rating." ***

    Abstract
    Reports results of the work of a new member of the ELINOR project team to review the development taking place in Z39.50 networked information retrieval protocol with a view to bringing the University's electronic library pilot systems, including ELINOR and the online catalogue into a single, unified system. Focuses particularly on the WWW client server environment

    Abstract
    By the mid 1980s online bibliographic systems retrieved excessively large sets. Conversely, with standard Boolean systems, searches retrieved commonly nothing or too few records. In Nov. 92, 32% of searches yielded nothing from a retrieval set averaging 98. Offers solutions to these problems using MELVYL as a case study. Examines how non topical data such as date, language and location of document can improve topical searches. Explains OASIS and front end phototyping. Discusses adaptive retrieval, strategic commands, expanded retrieval and developments of OASIS. Covers aggregation of filtered sets, related terms, automatic progressive truncation, the SUMMARIZE LIBRARIES command, filing and filtering and collection analysis
