    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
    Reports on a study of the search tactics used in searching the WWW and in dealing with difficulties such as too many postings and no relevant postings. Describes how the study was carried out, the analytical techniques used in it, and the results. Notes that with regard to tactics used to address search difficulties, no differences were found between searchers for texts and those for graphic information, and between those for known items and subject searches. Comments on the similarities and differences between the tactics used and and those used in online searching, including online catalogue searching

    Abstract
    Many information channels are available to students, but it is now clear how students select and use them. Reports results of a study of the information seeking behaviour of students at 2 US universities: the American University; and the District of Columbia University. The study aimed to investigate: the information channels used by students when they work on course related projects and how they select the channels; how they use ALADIN, an augmented OPAC that provides access to the holdings of the Washington Research Library Consortium and several commercial online databases; and how selected characteristics of students are related to their use of information channels. Students identified convenience and quality of data as the top 2 factors in their choice of information channel. Affirms the value of librarians and of formal information channels, suggests ways to augment the online catalogue, and reminds librarians that equal access to information technology does not necessarily lead to equal use
