    Abstract
    Evaluates the performance of 8 major Internet search engines in answering 21 real reference questions and 5 made up subject questions. Reports on the retrieval and relevancy ranking abilities of the search engines. Concludes that the search engines did not produce good results for the reference questions unlike for the subject questions. The best engines are identified by type of questions, with Infoseek best for the subject questions, and OpenText best for refrence questions

    Abstract
    Continued development of the Internet requires the development of efficient, easy-to-use search engines. Ideally, such development should call upon knowledge and skills from a variety of disciplines, including computer science, information science, psychology, and ergonomics. The current study is intended to determine whether search engines shows a pattern of interdisciplinarity. 2 disciplines were selected as the focus for the study: computer science, and library/information science. A citation analysis was conducted to measure levels of interdisciplinary research and publishing in Internet search engine design and development. The results show a higher level of interdisciplinarity among library and information scientists than among computer scientists or among any of those categorized as 'other'. This is reflected both in the types of journals in which the authors publish, and in the references they cite to support their work. However, almost no authors published articles or cited references in fields such as cognitive science, ergonomics, or psychology. The results of this study are analyzed in terms of the writings of Patrick Wilson, Bruno Latour, Pierre Bordieu, Fritz Ringer, and Thomas Pinelli, focusing on cognitive authority within a profession, interaction between disciplines, and information-gathering habits of professionals. Suggestions for further research are given

    Abstract
    The purpose of this paper is to determine some of the structural features of the classification schemes used in the directories (guides, channels) of search engines to organise information sources on the Internet. Ten search engines were examined at the main class level and the full hierarchies of a sample of three specific subjects were analysed in four of these engines, namely Excite, Infoseek, Lycos and Yahoo! It was found that there are major differences between the main classes of the search engines and those found in standard library schemes like Dewey, UDC and LCC. There are large gaps in subject coverage at main class level in the search engines and the general tendency is to use a topic-based approach in the formation of classes, rather than a discipline-based approach. The subdivision of the main classes is according to hierarchical tree structures, but a number of anomalies in this regard were identified. Another deviation from library classification theory is that various principles of division are employed to form classes at the same hierarchical level. In an analysis of citation orders many examples were found that conform to the principles followed in library classifications, but a number of inconsistencies in this regard were also noted

    Abstract
    Reports results of a study, conducted at Hawaii University, Department of Information and Computer Science, to understand the novide searchers' experience in learning to use a WWW search engine. Without prior searching instruction, undergraduate novives wrote structured self reports during their first session on a Web search engine. Users choose their own topics and followed written instructions that prompted them to describe thoughts and feelings during specified stages of the search; pre search formulation; search statement formulation; search strategy; and evaluation of the results. The sentences in the self reports were numbered and then coded according to their affective or cognitive function. The affective sentences reveal how users set goals and limit the scope of the cognitive operations. Search acts appear to be governed by an affective filter that organizes incoming information and provides criteria for ranking cognitive relevance to search goal. Content analysis identifies reasons users have for rating self confidence, stress level, satisfaction, usefulness, and success with future searches

    Abstract
    Reports the results of searches on 200 topics carried out on 5 Internet search engines (Magellan, Point, Lycos, InfoSeek and AltaVista). Describes the methodology followed and the results of the study. Gives a chart showing 30 of the search queries, with the performance of each search engine. Indicates some of the limitations of the search engines

    Abstract
    Reports a comparison of the retrieval effectiveness of the AltaVista, Excite and Lycos Web search engines. Describes a method for comparing the recall of the 3 sets of searches, despite the fact that they are carried out on non identical sets of Web pages. It is thus possible, unlike previous comparative studies of Web search engines, to consider both recall and precision when evaluating the effectiveness of search engines
