- Abstract
- User persistence in displaying postings is a significant human factor in the design of computer driven information systems, including online catalogs. Expert opinion and a study of users of a first generation online catalogue have suggested that users normally display no more than 30 to 35 postings. A follow up study on a second generation system with a larger database found that a greater proportion of users reported overload, but 100 postings (rather than 15) were considered 'too many'. Partially persistent users typically displayed 28 postings, but overloaded uses did not outnumber totally persistent users until postings retrieved exceeded 200. The findings suggest that, given sufficient resources, designers should still consider 30 to 35 postings typical persistence, but also justify treating 100 or 200 postings as a common threshold of overload

- Abstract
- There has been a flurry of constructive discussion and debate about the future of cataloging and the catalog, from FRBR and RDA on cataloging rules (with a focus on content) to next-generation discovery interfaces for the catalog (with a focus on carrier). A topic that is not receiving as much attention in the midst of these discussions is the scope of the library catalog. This article offers an opinion on the scope of the catalog in a research library, and the role of the catalogers in this time of transition. The article will also elicit some practical approaches that catalogers can take to reposition the catalog for improved user-access and resource discovery.

- Abstract
- The paper presents findings based on user feedback and opinion of online public access catalogues as tools for finding, identifying, and selecting bibliographic materials in a public library setting. Participants spoke their thoughts aloud while conducting known-item searches. The findings describe an iterative process of action, observation, identification, and emotion.

- 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.
