    Abstract
    As mentioned above, the guidelines are intended to apply to all types of catalogue, including Web-based catalogues, GUI-based interfaces, and Z39.50-web interfaces. The focus of the guidelines is on the display of cataloguing information (as opposed to circulation, serials check-in, fund accounting, acquisitions, or bindery information). However, some general statements are made concerning the value of displaying to users information that is drawn from these other types of records. The guidelines do not attempt to cover HELP screens, searching methods, or command names and functions. Thus, the guidelines do not directly address the difference between menu-mode access (so common now in GUI and Web interfaces) vs. command-mode access (often completely unavailable in GUI and Web interfaces). However, note that in menu-mode access, the user often has to go through many more screens to attain results than in command-mode access, and each of these screens constitutes a display. The intent is to recommend a standard set of display defaults, defined as features that should be provided for users who have not selected other options, including users who want to begin searching right away without much instruction. It is not the intent to restrict the creativity of system designers who want to build in further options to offer to advanced users (beyond the defaults), advanced users being those people who are willing to put some time into learning how to use the system in more sophisticated and complex ways. The Task Force is aware of the fact that many existing systems are not capable of following all of the recommendations in this document. We hope that existing systems will attempt to work toward the implementation of the guidelines as they develop new versions of their software in the future.

    Abstract
    Purpose - The objective of this study is to establish the opinion of users with respect to the awareness and utilisation of, as well as their satisfaction level with, the use of the online public access catalogue (OPAC). Design/methodology/approach - The paper deals with the applicability and utility of OPACs in five libraries in New Delhi, namely the Indian Institute of Technology; Jawaharlal Nehru University Library; Dr Zakir Husain Library, Jamia Millia Islamia; National Information System for Communication and Information Resources (NISCAIR); and the Defence Science Information and Documentation Centre (DESIDOC). A questionnaire was developed and distributed randomly to 128 users including undergraduates and post graduate students as well as MPhil. and PhD scholars. Users returned 115 completed questionnaires of which 100 were selected for analysis. Findings - The paper finds that the OPAC system has changed the traditional concept of access to library resources. It allows simple as well as complex searches. Document access is still one of the most important approaches of users to visit the library, and a study of the effectiveness of an OPAC is useful in this respect. Regarding results, sometimes users face problems of recall and precision. However, in some searches users are not able to find relevant documents on account of various factors. Data show that a high percentage of respondents are utilising the OPAC as a search tool for retrieving documents. Also, most of the users handle the OPAC themselves. Significantly, the satisfaction level of users was high with the OPAC facilities. Nevertheless, not many users are aware of the expert searches provided by OPAC. Originality/value - The paper focuses on many aspects of OPACs, particularly those in India. Librarians, especially those from developing nations, may choose their library automation software packages keeping in view the user's expectation with respect to OPACs.

    Abstract
    The discovery service (a search engine and service called WILBERT) used at our library at the Technical University of Applied Sciences Wildau (TUAS Wildau) is comprised of more than 8 million items. If we were to record all licensed publications in this tool to a higher level of articles, including their bibliographic records and full texts, we would have a holding estimated at a hundred million documents. A lot of features, such as ranking, autocompletion, multi-faceted classification, refining opportunities reduce the number of hits. However, it is not enough to give intuitive support for a systematic overview of topics related to documents in the library. John Naisbitt once said: "We are drowning in information, but starving for knowledge." This quote is still very true today. Two years ago, we started to develop micro thesauri for MINT topics in order to develop an advanced indexing of the library stock. We use iQvoc as a vocabulary management system to create the thesaurus. It provides an easy-to-use browser interface that builds a SKOS thesaurus in the background. The purpose of this is to integrate the thesauri in WILBERT in order to offer a better subject-related search. This approach especially supports first-year students by giving them the possibility to browse through a hierarchical alignment of a subject, for instance, logistics or computer science, and thereby discover how the terms are related. It also supports the students with an insight into established abbreviations and alternative labels. Students at the TUAS Wildau were involved in the developmental process of the software regarding the interface and functionality of iQvoc. The first steps have been taken and involve the inclusion of 3000 terms in our discovery tool WILBERT.
