- 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
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

- Abstract
- Subject access in the OPAC, as discussed in this article, is predicated on two different kinds of searching: subject (authority, alphabetic, or controlled vocabulary searching) or keyword (uncontrolled, free text, natural language vocabulary). The literature has focused on demonstrating that both approaches are needed, but very few authors address the need to integrate keyword into authority searching. The article discusses this difference and compares, with a query on the term garbage, search results in two online catalogs, one that performs keyword searches through the authority file and one where only bibliographic records are included in keyword searches.

- One of the most common errors in cataloguing library materials involves miscoding of the nonfiling indicator of title fields. Notes the extent of the problem and its negative effect on searching in the library's online catalogue and surveys how librarians have approached solutions to the problems. Describes how the major library automation system address this problem

- Abstract
- Reports results of a questionnaire survey of UK academic libraries to determine the level of use of online public access catalogues (OPACs) and the development of inhouse subject indexes. 75 respondents reported having commercial systems and 7 reported inhouse systems. Data includes: named systems in use and numbers of libraries using each system; percentages of bibliographic records in machine readable format; types of materials; and record formats (UKMARC, LCMARC etc.) Reports the most common access points for searching the OPACs (author, keyword), methods of generating terms to be used for subject searching, subject heading sources (LCSH, MeSH, PRECIS) and classification schemes (Dewey (DDC), UDC). Results show that all universities and polytechnics now have OPACs and only the smaller colleges do not. OPACs are moving towards comprehensive covergae of academic library stocks with the MARC record the most popular format. The 3 main subject access strategies involve: LCSH, inhouse strategies, and strategies not based on controlled terminolgy. Draws heavily on the results of an earlier survey by Fran Slack (Vine 72(1988) Nov., S.8.12)

- Abstract
- Describes the availability, use and value of Z39.50, an international standard which allows a librarian accessing a database on one computer platform to search an OPAC hosted on another computer with a totally different database structure. Experiences of those working with the standard are given, and its use by the European Union IRIS project to link 6 major Irish research libraries is examined. Despite some problems encountered with different forms of author cataloguing and possible competition from the WWW, the standard is seen as possessing considerable strengths, for example in searching different catalogues and presenting the results in a standard format on screen, which justify the continuing interest of librarians

- Abstract
- The Venice University Institute of Architecture has developed Easyweb, a software package to integrate its heterogeneous non-compatible bibliographic and multimedia databases, standardise access and create internal links, by transferring all existing OPAC applications to the Web. Features include importation of UNIMARC data, multiple window searching, multibase searching and special applications, e.g. circulation management. Easyweb is notable user friendly and has become the point of reference for OPACs in Italy

- Abstract
- Subject searching is the most common but also the most conflictive searching for end user. The aim of this paper is to check how users expressions match subject headings and to prove if knowledge structure used in online catalogs enhances searching effectiveness. A bibliographic revision about difficulties in subject access and proposed methods to improve it is also presented. For the empirical analysis, transaction logs from two university libraries, online catalogs (CISNE and FAMA) were collected. Results show that more than a quarter of user queries are effective due to an alphabetical subject index approach and browsing through hypertextual links. 1. Introduction Since the 1980's, online public access catalogs (OPAC's) have become usual way to access bibliographic information. During the last two decades the technological development has helped to extend their use, making feasible the access for a whole of users that is getting more and more extensive and heterogeneous, and also to incorporate information resources in electronic formats and to interconnect systems. However, technology seems to have developed faster than our knowledge about the tasks where it has been applied and than the evolution of our capacities for adapting to it. The conceptual model of OPAC has been hardly modified recently, and for interacting with them, users still need to combine the same skills and basic knowledge than at the beginning of its introduction (Borgman, 1986, 2000): a) conceptual knowledge to translate the information need into an appropriate query because of a well-designed mental model of the system, b) semantic and syntactic knowledge to be able to implement that query (access fields, searching type, Boolean logic, etc.) and c) basic technical skills in computing. At present many users have the essential technical skills to make use, with more or less expertise, of a computer. This number is substantially reduced when it is referred to the conceptual, semantic and syntactic knowledge that is necessary to achieve a moderately satisfactory search. An added difficulty arises in subject searching, as users should concrete their unknown information needs in terms that the information retrieval system can understand. Many researches have focused an unskilled searchers' difficulties to enter an effective query. The mental models influence, users assumption about characteristics, structure, contents and operation of the system they interact with have been analysed (Dillon, 2000; Dimitroff, 2000). Another issue that implies difficulties is vocabulary: how to find the right terms to implement a query and to modify it as the case may be. Terminology and expressions characteristics used in searching (Bates, 1993), the match between user terms and the subject headings from the catalog (Carlyle, 1989; Drabensttot, 1996; Drabensttot & Vizine-Goetz, 1994), the incidence of spelling errors (Drabensttot and Weller, 1996; Ferl and Millsap, 1996; Walker and Jones, 1987), users problems

- Abstract
- This paper reports on the successful introduction of a sophisticated online catalogue system at the library of the Scott Polar Research Institute, Cambridge, using the Muscat program package. The system provides to both end-users and library staff a choice between boolean searching on keywords and access using relevance feedback based on free text in English, mixed with UDC classification numbers. The system is implemented on an IBM 3084 computer. Significant benefits from the application of relevance feedback are reported with 10,000 records on file.

- Abstract
- For decades print pathfinders have complemented card catalogues and been useful reference tools. They are overlooked as components of online catalogues, even though they can extend the depth of the catalogue. To encourage librarians to consider integrating pathfinders into online catalogues discusses problems in OPAC searching, describes the value and styles of pathfinders, and illustrates how to include them in a NOTIS system

- Abstract
- Examines 3 aspects of keyword searching to see if defaulting to keyword searches might serve as a solution to the problems users find when performing subject searches in OPACs. Investigates if keyword searching produces useful results; if people who use keyword searches to find information on a subject report that they are satisfied with the results; and how keyword searching and controlled vocabulary searching are offered and explained in currently available OPAC interfaces. Concludes that both keyword and controlled vocabulary searching ought to be easily available in an OPAC, and that improvements need to be made in explanation and help offered to subject searchers
