    Abstract
    This article proposes a model of document selection by real users of a bibliographic retrieval system. It reports on Part 1 of a longitudinal study of decision making on document use by academics during a actual research project. (Part 2 followed up the same users on how the selected documents were actually used in subsequent stages). The participants are 25 self-selected faculty and graduate students in Agricultural Economics. After a reference interview, the researcher conducted a search of DIALOG databases and prepared a printout. The users selected documents from this printout, They were asked to read and think aloud while selecting documents. There verbal reports were recorded and analyzed from a utiliy-theoretic perspective. The following model of the decision-making in the selection process emerged: document information lemenets (DIEs) in document records provide the information for judging the documents on 11 criteria (including topicality, orientation, quality, novelty, and authority); the criteria judgments are comninded in an assessment of document value along 5 dimensions (Epistemic, functional, conditional, social, and emotional values), leading to the use decision. This model accounts for the use of personal knowledge and decision strategies applied in the selection process. The model has implications for the design of an intelligent document selection assistant

    Abstract
    Reports results of a comparative analysis of choice and form of main entry in the monograph cataloguing of the LoC and that of the British Library and the national libraries of Canada and Australia in 1982 and 1989, to examine the level and kind of consistency achieved in Anglo-American descriptive cataloguing. The overall aim of the project was to investigate the achievement of UBC and the implicit idea that bibliographic records created by the national bibliographic agency (NBA) of one country should be acceptable, without modification, to the NBAs of other countries. Part 2 provides an analysis of patternsaffecting the form of main entry headings (personal and corporate names), choice and form of uniform titles and titles proper, and miscellaneous descriptive cataloguing elements. These steps are intended to lead to a common MARC format, a common file of authority records, and, ultimately, a common file of bibliographic records for the cataloguing agencies of the major English speaking countries. concludes that Barbara Tillett's vision of 1 seamless bibliographic system, either real or virtual, looks realizable over a 5 to 10 year horizon

    Abstract
    We propose a novel method for automatically adjusting paprameters in ranked-output text retrieval systems to improve retrieval performance. A renaked-output text retrieval system implements a ranking function which orders documents, placing documents estimated to be more relevant to the user's query before less relevant ones. The systems adjusts its parameters to maximize the match between the systems's document ordering and a target ordering. The target ordering is typically given by user feedback on a set of sample queries, but is more generally any document preference relation. We demonstrate the utility of the approach by using it to estimate a similarity measure (scoring the relevance of documents to queries) in a vector space model of information retrieval. Experimental results using several collections indicate that the approach automatically finds a simimilarity measure which performs equivalently to or better that all 'classic' similarity measures studied. It also performs within 1% of an estimated optimal measure (found by exhaustive sampling of the similarity measures). The method is compared to two alternative methods: a perceptron learning rule motivated by Wong and Yao's (1990) Query Formulation method, and a Least Squared learning rule, motivated by Fuhr and Buckley's (1991) Probabilisitc Learning approach. Though both alternatives have useful characteristics, we demonstrate empirically that neither can be used to estimate the parameters of the optimal similarity measure

    Abstract
    This study investigated the effects of subject knowledge and search experience on novices' and experienced searchers' use of search tactics in online searches. Novice and experienced searchers searched a practice question and two test questions in the ERIC database on the DIALOG system and their use of search tactics were recorded by protocols, transaction logs, and observation. Search tactics were idetified from the literature and verified in 10 pretests, and nine search tactics variables were operationalized to describe the differences between the two searcher groups. Data analyses showed that that subject knowledge interacted with search experience, and both variables affected searchers' behavior in four ways: (1) when questions in their subject area were searched, experience affected searchers' use of synonymous terms, monitoring of the search process, and combinations of serch terms; (2) when questions outside their subject areas were searched, experience affected searchers' reliance on their own terminology, use of the thesaurus, offline term selection, use of synonymous terms, and combinations of search terms; (3) within the same experience group, subject knowledge had no effect on novice searchers; but (4) subject knowledge affected experienced searcher's reliance on their own language, use of the thesaurus, offline term selection, use of synonymous terms, monitoring of the search, and combinations of search terms. The results showed that search experience affected searchers' use of many search tactics, and suggested that subject knowledge became a factor only after searchers have had a certain amount of search experience

    Abstract
    The primary aim of the study was to investigate the effect of the absence of postings information on online searches and searching behaviour and these results were reported in Journal of information science 20(1994) no.1. The secondary aim, reported here, was to assess the cognitive styles of the participants to ensure that the population was sufficiently vareid in this respect and to investigate possible correlations between cognitive ability and searching behaviour. Throughout the project, searches were made by postgraduates at the department of information studies, University of Sheffield using the LISA database on CD-ROM. A total of 67 searchers carried out 275 searches, both with and without postings information. Reports significant differences in both searching behaviour and search outcomes obtained by those with different learning styles, with and without postings information. Significant correlations were found between cognitice styles and online searching. Searchers characterized by different learning styles tend to adopt different search strategies and strategies associated with comprehension and operation learning styles result in qualitatively different searching performance. Searching approaches associated with a versatile style are the most effective. Making feedback in the form of postings available enables comprehension and operation learners, and field independent searchers, to change their apporach in qualitatively different ways. Other findings are reported and discussed

    Abstract
    This study compared the search features and retrieval performance of Yahooligans!, Ask Jeeves for Kids, and Super Snooper on identical searches. This extended the earlier research conducted by Bilal (1999), which examined the cognitive, affective, and physical behaviors of twenty-two 7th grade science students' use of Yahooligans! search engine. The three types of searches the students formulated in Yahooligans! on an imposed fact-driven query were here conducted in Ask Jeeves for Kids and Super Snooper. The retrieval performance criteria of the three engines included: (1) retrieval output, (2) relevance, (3) overlap in results, and (4) redundancy. A matrix of features (e.g., database coverage, search interface, search capabilities, retrieval interface, filtering, feedback, online help, FAQs, and advertisements) was developed to compare the engines. The performance of the natural language capability embedded in Ask Jeeves for Kids was evaluated by comparing the results retrieved directly from Yahooligans! to those Ask Jeeves for Kids returned from Yahooligans! on identical searches.The. results shed light on the strengths and weaknesses of each engine and appropriateness to specific types of queries. Yahooligans! was the most effective on keyword searching. Super Snooper returned the highest number of hits but with zero relevance on all types of searches. Ask Jeeves for Kids was successful only on one keyword search and failed both the natural language phrase and multiple keyword. Implications are made for improving the engines' design, retrieval performance, and search features, as well as for user instruction

    Abstract
    Derivative bibliographic relationships are the primary relationships that exist among the members of a bibliographic family--the set of interrelated works where the relationships among entities express shared semantic or linguistic activity. Derivative bibliographic relationships exist between any new conception of a work and its original source (the progenitor), or its successor, or both. Discipline was a poor predictor of derivative relationships in prior studies of derivative bibliographic relationships. For the present study random samples of works were drawn from the catalogs of the Bobst Library, New York University, and the Burke Library, Union Theological Seminary, New York. Two sites were chosen to allow a test of the differences in collection development patterns between a university research library and a theological library. Bibliographic families were compiled for each work. Results indicate: 1) derivative bibliographic relationships exist for somewhere between one-half and two-thirds of theological works in this study; 2) there is little difference in proportions of derivative bibliographic relationships or in the size of bibliographic families between the two collections; 3) there is a positive correlation between the age of the progenitor work and the size of the bibliographic family); 4) there are significant gaps in coverage of theological bibliographic families online; 5) there is some evidence of differing patterns of derivation between Judaic and Islamic literature and Christian literature; 5) forms and genres are useful in a limited way for predicting the incidence of derivative relationships in theological literature

    Abstract
    Tenopir and King (1998) reported journal articles five years and older are found through "citations" among university scientists 13.3% of the time and among non-university scientists 42.1 % of the time. University scientists ranked finding journal articles from "other persons" and "other" more than by "citations." Non-university scientists " ranked using "citations the highest for finding older articles. Clearly this shows linking online journals to the full text of older cited articles would prove to be a great convenience to scientists reading recent articles. This research discusses how to make the best choices for converting journals retrospectively to digital and online format. The Literature cited was analyzed to find 1.) the age of the literature used over time and 2.) the mix of types of literature of the discipline. The disciplines studied were ecology and biochemistry because of several differences between them. Based upon the results, differences do exist between the two disciplines in the ages of literature used. The results show that if 98 percent or more of the literature is included, retrospective conversion for discipline of ecology would be more valuable than would biochemistry for the same number of journal articles. The second part of the study discussed some possible screening methods before doing an extensive citation analysis of a discipline's journal articles. Ecology articles cited books seven times more than did biochemistry articles. This may be an additional indicator that ecology has an older, more stable body of literature when compared to biochemistry. This and additional indicators will be helpful in the initial identification

    Abstract
    In this paper, we report on the second part of an empirical study designed to observe how users interact with World Wide Web resources. Applying a holistic approach, the researches examine users' cognitive, affective, and physical behaviors during user-Web interaction in order to understand better the nature of information retrieval on the Web, the needs of Web users, and the problem-solving strategies Web users employ. From analyses and the participant verbalizations collected during monitored searches, the researchers developed a taxonomy of problem solving strategies. The coding scheme was developed based on a content analysis of the integrated process data. Information from triangulation follow-up with participants via anonymously completed questionnaires, the taxonomy, and analyses of search transcripts were collected to determine 1) what problems users encountered during the interaction and how users solved these problems; and 2) which problem-solving strategies Web users considered and selected for finding factual information. The focus of the coding was on the participants' cognitive, affective, and physical behaviors in response to the components of the problems encountered, which included problems of the following types: Web interfaces, users' mental models, and the Web information sources. Searching behavior and problem-solving patterns are described and interpreted within the relevant situational context and the problems users encountered are identified and analyzed. Both the problems users faced and their problem-solving approaches endeavored evidence a strong reliance on mental models of the features available on sites, the location of those features, and other interface design concepts

    Abstract
    This study compares the traditional model of the reference interview with a new model based on online information process. The research objectives were three-fold: 1. to develop and test a new model of the reference interview in which the Web becomes an important component; 2. to determine which model is most effective in satisfying user needs; 3. To rate models according to perceptions and evaluations of users and librarians. Observing traditional reference interview process reveals that a user's initial query is followed by a series of questions posed by the librarian for the purpose of query clarification. Interpersonal communication facilitates this process. Predictable problems and difficulties for both user and librarian often arise. As users increasingly associate research with online searching and the Internet, meeting user expectations that reference services will integrate new technologies seems not only unavoidable but also highly desirable. Still, Internet use in libraries remains generally isolated from librarian/user process - users surf solo and often do not use collections or benefit from the librarian's expertise in onlilne searching. The Web offers librarians new opportunities to present users with a rich array of information from which they can examine, compare, evaluate and select information, focus a topic, learn of new contexts and perspectives, and make informed choices. Findings of this study offer fresh perspectives on reference interview process and lend support to the adoption of a new reference model which importantly shifts its venue from a person to person process, to one in which information itself provides the platform for user and librarian interaction

    Abstract
    This article describes design considerations of two interrelated programs that together make Learning Portfolio (LEAP) prototype system for accessing engineering information for engineers. The two programs are: Engineering Information Sources and Access (EISA), implemented as a Web-based self-learning prototype system; and Information Sources that Every Engineer should Know; ISEEK adds embedded instructional layer, representative queries, and constitutes the core layer of engineering sources for a beginner engineering student. Of analytical significance, the project has (1) defined indicators of information literacy (IL) for engineering students; (2) developed IL questionnaire to test engineering students' IL skills; (3) developed information literacy profile of engineering students under study; (4) assessed existing information resources, tools and search techniques. Of practical significance, we have: (5) applied students' responses in the design of EISA; (6) implemented the EISA information literacy program for engineers; (7) developed a series of hypertext-based tutorials each dealing with a specific IL issue; and (8) proposed set of the four design principles (i.e., understanding the user; active learning; conceptual model of teaching; and modularity). Finally, the article identifies and discusses future work

    Abstract
    In order to compare the value of subject descriptors and title keywords as entries to subject searches, two studies were carried out. Both studies concentrated on monographs in the humanities and social sciences, held by the online public access catalogue of the National Library of the Netherlands. In the first study, a comparison was made by subject librarians between the subject descriptors and the title keywords of 475 records. They could express their opinion on a scale from 1 (descriptor is exactly or almost the same as word in title) to 7 (descriptor does not appear in title at all). It was concluded that 37 per cent of the records are considerably enhanced by a subject descriptor, and 49 per cent slightly or considerably enhanced. In the second study, subject librarians performed subject searches using title keywords and subject descriptors on the same topic. The relative recall amounted to 48 per cent and 86 per cent respectively. Failure analysis revealed the reasons why so many records that were found by subject descriptors were not found by title keywords. First, although completely meaningless titles hardly ever appear, the title of a publication does not always offer sufficient clues for title keyword searching. In those cases, descriptors may enhance the record of a publication. A second and even more important task of subject descriptors is controlling the vocabulary. Many relevant titles cannot be retrieved by title keyword searching because of the wide diversity of ways of expressing a topic. Descriptors take away the burden of vocabulary control from the user.
