    Abstract
    Discusses the problems encountered by elementary school children in retrieving information from catalogues, either traditional card catalogues or OPACs. Describes an alternative system of classification using colours and symbols that was developed in The Common School of Amherst, Mass. The case study found that children do have the ability to use a classification scheme that is keyed to their developmental level and that employs both colours and symbols to facilitate their search efforts

    Abstract
    In this paper, we define and present a comprehensive classification of user intent for Web searching. The classification consists of three hierarchical levels of informational, navigational, and transactional intent. After deriving attributes of each, we then developed a software application that automatically classified queries using a Web search engine log of over a million and a half queries submitted by several hundred thousand users. Our findings show that more than 80% of Web queries are informational in nature, with about 10% each being navigational and transactional. In order to validate the accuracy of our algorithm, we manually coded 400 queries and compared the results from this manual classification to the results determined by the automated method. This comparison showed that the automatic classification has an accuracy of 74%. Of the remaining 25% of the queries, the user intent is vague or multi-faceted, pointing to the need for probabilistic classification. We discuss how search engines can use knowledge of user intent to provide more targeted and relevant results in Web searching.

    Abstract
    This study explores the navigation behaviour of all users of a large web service, Renardus, using web log analysis. Renardus provides integrated searching and browsing access to quality-controlled web resources from major individual subject gateway services. The main navigation feature is subject browsing through the Dewey Decimal Classification (DDC) based on mapping of classes of resources from the distributed gateways to the DDC structure. Among the more surprising results are the hugely dominant share of browsing activities, the good use of browsing support features like the graphical fish-eye overviews, rather long and varied navigation sequences, as well as extensive hierarchical directory-style browsing through the large DDC system.

    Abstract
    Investigates what effect the shelf classification of fiction had on the way that library users in the 2 branch libraries of Kajanni, Finland, use the library's stock of fiction and how they loan fiction. In 1 library the fiction stock was divided in 11 shelf categories, based on genres of fiction - in the other no changes were made. The books were also indexed and classified in the library's database. The project lasted for 3 years and the results were gathered by interviewing clients and making statistical analysis on loans in both libraries

    Abstract
    Current online catalogs have problems providing reasonable subject access, often resulting in searches with too few or too many hits. These problems can be improved by enhancing MARC records, building semantic networks through cross-references, and linking subject headings to classification numbers. This paper describes a pilot project to design a hypertext search engine using these principles

    Abstract
    Reports a comparative study of OPAC use designed to investigate whether there are fewer zero or no direct hits due to users' misconceptions today than 10 years ago. Data from PEGASUS, Columbia University Law Library's INNOPAC based OPAC on failed searches was compared with that from an earlier study (see Cataloging and classification quarterly 4(1984) no.3, S.1-17) of LUIS, Northwestern University's NOTIS based OPAC. No direct hits resulting from a misconception of the system were found to constitute only half of the no direct hits compared with the corresponding category of the earlier study

    Abstract
    The study reported here investigated the search behaviour patterns of nanoscience and nanotechnology searchers as revealed by transaction log analysis of the NANOnetBASE electronic book digital library. This paper examines the patterns and strategies of nano searchers' query formulation and reformulation, then explores the extent of interdisciplinarity in search queries using the INSPEC and Compendex thesauri. The results show certain query formulation patterns associated with searching in an emerging and interdisciplinary area of nanotechnology such as: the use of multiword and compound query terms, extensive use of search terms beginning with the prefix "nano," hyphenated terms, spelling variations, a large number of query reformulations, and the use of acronyms. The results also indicate that 62% of the unique top terms resulting from mapping users' query terms to the INSPEC Classification codes represented two or more disciplines, specifically terms associated with the Classification code "A" representing "physics." The results have implications for information organization and representation, user interface design and federated searching in digital libraries and multi-subject databases.

    Abstract
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.
