This paper explores resource discovery issues relating to New Zealand/Aotearoa information on the WWW in the twenty‐first century. Questions addressed are: How do New Zealand search engines compare with global search engines for finding information relating to New Zealand? Can search engines find everything that is available on the web? What are effective strategies for finding information relating to New Zealand on the web? What is the quality of NZ information on the web? What can librarians do to make NZ information more accessible on the web? Based on a study, it concludes that neither local nor global search engines are by themselves sufficient, and that to maximize retrieval a variety of engines is necessary. The NZ librarian can play a role in ensuring that NZ information is made both available and accessible. Although the paper discusses the situation in New Zealand, the results and conclusions are applicable to other countries.

This article considers what contribution traditional library practices — identification, selection, organisation and retrieval — can make to managing networked information, and how those practices need to be updated to take account of the special difficulties of the Internet. The answer is found in cooperation. Cooperation between librarians and authors in the creation of metadata. International cooperation between librarians to select resources. The article defines a workflow for cooperation in both fields, and proposes a library search engine to hold jointly created records and a catalogue of Websites online to support selection.

A ‘World Wide Web search engine’ is defined as a retrieval service, consisting of a database (or databases) describing mainly resources available on the World Wide Web (WWW), search software and a user interface also available via WWW. After intro ducing early Internet search engines, which are pertinent as precursors for the current range of WWW search engines, the problems of searching the WWW (link persistence, lack of integrated search software) and the resulting search engine types (keyword or directory) are analysed. Search engines of all types are then compared across their generic features (database content, retrieval software, and search interface), rather than on a search engine by search engine basis. Finally, wider information access issues aris ing from the nature of the Internet and web search engines are considered, and a general strategy for using web search engines is proposed.

Bates' information search tactics have been influential in the practice and teaching of online searching since they were published in 1979. This paper is about using information search tactics to search the internet, and aims to present a set of tactics useful in the practice and teaching of internet searching.

Tactics used on the internet were gathered from the literature, web sites, and the author's experience of internet searching. These were compared with the information search tactics, and refined into a set of internet search tactics.

The article presents 34 internet search tactics: 18 of the original Bates tactics, interpreted in the context of the internet, and 16 new tactics. While many of the information search tactics are relevant, effective internet searching requires recognition of the role of relevancy ranking and full text searching in search engines. The uncontrolled nature of the internet means that evaluation of information resources is an integral part of internet searching, so a group of evaluation tactics have been proposed.

The tactics provide a framework for teaching effective internet searching.

Bates' information search tactics do not appear to have been applied as a whole to searching the internet. The proposed tactics will be useful for librarians and researchers who need to carry out effective searching on the internet, and for information literacy education. Research into information seeking and search interfaces will be informed by the tactics.

The literature of the evaluation of Internet search engines is reviewed. Although there have been many studies, there has been little consistency in the way such studies have been carried out. This problem is exacerbated by the fact that recall is virtually impossible to calculate in the fast changing Internet environment, and therefore the traditional Cranfield type of evaluation is not usually possible. A variety of alternative evaluation methods has been suggested to overcome this difficulty. The authors recommend that a standardised set of tools is developed for the evaluation of web search engines so that, in future, comparisons can be made between search engines more effectively, and that variations in performance of any given search engine over time can be tracked. The paper itself does not provide such a standard set of tools, but it investigates the issues and makes preliminary recommendations of the types of tools needed.

An emerging, globally Web‐based Chinese language virtual library offers unprecedented content availability and user accessibility. Virtual and physical libraries are defined, and compared, in terms of bibliographical searching. Then, the size of the Chinese language virtual library is estimated and its future development is predicted. The quantitative analysis concentrates on the content of this virtual library through examining the subject directories of more than 100 of its search engines. The findings show that 20 percent of the subject categories provide 80 percent of online access activities. Many subject categories characterise values of the Chinese‐speaking world. Discussion continues with structural and functional analyses of Chinese language search engines that support this virtual library. Further, an analytic overview is presented of Chinese language applications that render the necessary and sufficient computational linguistic conditions for utilising Chinese language online resources.

The purpose of this paper is to investigate the role of Google in everyday online searching activities of Swedish teenagers in different contexts.

The study is qualitative and material has been produced through interviews and observations in two different schools with participants aged 15-16. Goffman’s frame analysis provides the analytical lens for studying how activities are assigned meaning.

Three different framings in relation to using Google and googling are identified in the material: Google and fact-finding, Google as a neutral infrastructure, and Google as an authority. There is an interplay between activity, context, and interaction in defining the role of Google. In relation to school, the fact-finding framing is more pronounced whereas the infrastructure framing comes forth more in their free time activities. The authority framing cuts across both framings and underpins their trust in the search engine.

The study addresses the way that Google is embedded in online activities and how the search engine is viewed in various contexts, as well as how it is made invisible in some contexts. Previous research has not addressed Google’s role in specific in relation to various everyday uses.

This paper reports findings from the first annual cycle of a three‐year research project on the provision and use of electronic information systems (EIS) within higher education in the UK. The project, JISC User Surveys: Trends in Electronic Information Services (JUSTEIS), was funded by the Joint Information Systems Committee (JISC) and undertaken at the University of Wales, Aberystwyth (UWA). Students, academics and library staff in 25 universities were surveyed using critical incident and critical success factors methodologies to ascertain the range and nature of EIS use. Provision of these systems by higher education institutions was also investigated via an analysis of their library websites. The findings reported in this paper focus on student use and the purposes for which EIS are employed, and reveal the limited array of EIS used and the ad hoc nature of search strategies adopted across undergraduate and postgraduate bodies within a range of disciplines. There appears to be little or no variation in the pattern of EIS use by the various student groups studied – the effect of the Internet on information seeking by students is hugely significant and the more formal resources, such as JISC‐negotiated resources are little used. There is little evidence of coherent search strategies used by students. Recommendations for both the JISC and higher education are offered.

This paper presents an evaluation of a commercially available intelligent search agent for the Internet. Search robots and search engines can be of great help in finding information on the Internet, but their different features and sometimes their unfriendly interfaces can be confusing. Some expect that intelligent search agents could solve these problems. But most of these applications are not yet on the market, and the few that are: do they really perform? One of the few commercially available search agents is Autonomy, from Autonomy Corporation. Its concept is promising to professional users: the natural language processing of the query, the take‐over of repetitive jobs, an integrated interface for searching and managing information, and the sharing of knowledge with other users. The test in this article, however, reveals that the product is not yet ready to challenge the Internet search indexes which, in the test cases, perform better than Autonomy does with regard to recall and precision of information retrieval. Moreover, Autonomy does not give enough feedback to control the search action.
