    Abstract
    The lack of complete and accurate citations for referenced works is a persistent and significant problem in scholarly writing. The advent of new froms of electronic publishing, especially hypermedia, has the potential for either aggravating or alleviating this problem. Incorrect and missing citations will become more prevalent (and, indeed, have become so within large bibliographic databases) without a concerted and ccoperative effort on the part of systems developers to provide adequate references and the means for easily accessing and downloading them. Examines some of the basic issues involved in the problem of maintaining the critical authorship links between source and expression in one specific form of electronic publishing - hypermedia - and proposes some solutions

    Abstract
    This article reports the analysis of two samples of search logs from a commercial image provider over a 1-month period. The study analyzes image searches and queries, user query modification strategies, and user browsing and downloading of results. Unique term searches are less frequent than earlier research has shown; descriptive and thematic queries are more common. Boolean searching, although heavily employed, appears to be ineffective and leads to query modifications. Although there was a large amount of query modification (61.7% of queries across the two sampies), the tactics overall do not appear to be carefully thought out and seem to be largely experimental. Given the willingness to modify queries but the inability to do so in an effective way, more support for query modification may be beneficial.
