    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
    Investigates the retrieval capabilities of 6 Internet search engines on a simple query. Existing work on search engine evaluation considers only the first 10 or 20 results returned by the search engine. In this work, all documents that the search engine pointed at were retrieved and thoroughly examined. Thus the precision of the whole retrieval process could be calculated, the overlap between the results of the engines studied, and an estimate on the recall of the searches given. The precision of the engines is high, recall is very low and the overlap is minimal
