- 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
- A research project in progress at Middlesex Polytechnic is examining the problems of providing adequate subject access from MARC-based cataloguing systems. Various forms of printed index are being evaluated and an experimental OPAC is being designed. The PRECIS RIN file will be tested as a basis for online thesaural control and as a browsing facility

- 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
- This paper examines some traditional information searching methods and their role in Hungarian OPACs. What challenges are there in the digital and online environment? How do users work with them and do they give users satisfactory results? What kinds of techniques are users employing? In this paper I examine the user interfaces of UDC, thesauri, subject headings etc. in the Hungarian library. The key question of the paper is whether a universal system or local solutions is the best approach for searching in the digital environment.

- 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
- The construction and updating of indexing languages depend on the organization of their hierarchical structures in order to determine the classification of related terms and, above all, to allow a constant updating of vocabulary, a condition for knowledge evolution. The elaboration of an indexing language for online catalogs of libraries' networks is important considering the diversity and specificity of knowledge areas. From this perspective, the present paper reports on the work of a team of catalogers and researchers engaged in the construction of a hierarchical structure of an indexing language for an online catalog of a university library's network. The work on hierarchical structures began by defining the categories and subcategories that form the indexing language macrostructure by using the parameters of the Library of Congress Subject Headings , the National Library Terminology and the Vocabulary of the University of São Paulo Library's system. Throughout the stages of the elaboration process of the macrostructure, difficulties and improvements were observed and discussed. The results enabled the assessment of the hierarchical structures of the languages used in the organization of the superordinate and subordinate terms, which has contributed to the systematization of operational procedures contained in an indexing language manual for online catalogs of libraries.

- 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
- At the end of 2005, impending digitization efforts and several developments related to the creation of access and discovery tools for informational and cultural objects resulted in a series of responses that continue to ripple throughout the library, museum and archive communities. These developments have broad implications for all three communities because of the goals shared by each in the creation of description, control and enhanced access to informational and cultural objects. This position paper will consider new implementations of faceted navigation and browsing features in online catalogs. It is also a response to challenges to develop interwoven approaches to the study of information seeking and the design and implementation of search and discovery systems. Urgently needed during this time of experimentation, development and implementation is a framework for system evaluation and critical analysis of needed and missing features that is grounded in traditional principles, borne out by practice. Such a framework could extend feature analysis protocols established during the early years of online catalog development.

- 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." ***
