    Abstract
    Expanded hours of access and the reduction of peak system loads are often cited as advantages of remote access to OPACs. This argument is based on the assumption that remote users search OPACs when libraries are closed or when there is low internal use. The study tested this assumption by performing a transactional log analysis of the remote and internal use of the OPAC at the Research Libraries of the New York Public Library. Analysis showed that pateerns of remote and internal use differed greatly. A large part of the remote searching occured when the Research Libraries were closed. Compared to internal searching, remote searching was distributed more evenly over the course of the day and the week. Results show that remote access expands the hours of use of the Online catalogue and has potential to reduce peak system loads at the Research Libraries

    Abstract
    Describes a study to investigate end user understanding of subdivided subject headings in their current form and in the form proposed by the first recommendation of the Library of Congress Subject Subdivisions Conference. The impetus for this study was a charge by the Subject Analysis Committee of the ALA to respond to the first recommendation of the LC Subject Subdivisions Conference that proposed standardizing the order of subject subdivisions. Questionnaires bearing subdivided subject headings in the 'current' form and in the form proposed were distributed to users and professional cataloguers who were asked for the meaning of individual headings. The end users' responses to cataloguers' responses were compared to determine end users' level of understanding of subdivided subject headings. An analysis of end user interpretations demonstrated that they interpreted the meaning of subject headings in the same manner as cataloguers about 40% of the time for 'current' forms of subject headings and about 32% of the time for 'proposed' forms of subject headings. Concludes with specific recommendations about the first recommendation of the LC Subject Subdivisions Conference and general recommendations about increasing end user understanding of subdivided subject headinbgs

    Abstract
    In this study descriptions of a novel by 100 users at 2 Swedish public libraries, Malmö and Molndal, Mar-Apr 95, were compared to the index terms used for the novels at these libraries. Describes previous systems for fiction indexing, the 2 libraries, and the users interviewed. Compares the AMP system with their own model. The latter operates with terms under the headings phenomena, frame and author's intention. The similarities between the users' and indexers' descriptions were sufficiently close to make it possible to retrieve fiction in accordance with users' wishes in Molndal, and would have been in Malmö, had more books been indexed with more terms. Sometimes the similarities were close enough for users to retrieve fiction on their own

    Abstract
    Critiques of subject access standards in LIS literature have addressed biases of gender, sexuality, race, age, ability, ethnicity, language and religion as limits to the representation of diversity and to effective library service for diverse populations. The current study identifies and analyzes this literature as a basis for ameliorating systemic bias and to gather the existing literature for wider accessibility. The study analyzes five quantitative variables: standards discussed, categories of problems, marginalized groups and topics discussed, date, and basis of conclusions (research or experience). Textual analysis reveals that basic tenets of subject access-user-focused cataloguing, objectivity, and standardization-are problematized in the literature and may be the best starting point for future research. In practice, librarians can work to counteract systemic problems in the careful and equitable application of standards and their adaptation to local contexts.

    Abstract
    Data from Westminster Libraries on membership, borrowing frequency and stock use is compared with significant studies of public library use from the last 50 years. The article examines the extent of public library use, and the social and demographic factors influencing use. Analysis of book and audio-visual stock use indicates the concentration of demand on a few titles and subjects, and the relationship to what is in demand commercially. Aspects of public library use have remained constant over at least the last 50 years, and across geographical boundaries. Public libraries are used principally for leisure, for borrowing recent fiction, for useful non fiction related to immediate life interests, and for pop music. Quantitative data from library systems provides a different, probably more accurate, picture of the nature and extent of public library use.

    Abstract
    The authors have studied the transaction counts from two and one-half years activity at the public use terminals of the Ohio State University Libraries' prototype online card catalog to determine what search options academic library patrons use the most often and whether this pattern varies from that reported in major catalog use studies. The preliminary findings indicate significant differences in search strategy that may result from a unique user group that prefers to search the online catalog, more useful searches in the online system, or special search patterns imposed by the computer hardware itself. Both the different searches used by patrons and why they choose them should be important factors in the design of future online catalogs

    Abstract
    This article reports on a low-cost study of the transaction log of an online public access catalog at an academic library. The three goals of the study were to determine failure rates, to study usage patterns, and to investigate problable causes of patron problems when using the OPAC. The study found that failure rates (defined as those searches that produced zero hits) of approximately 40% are common, and that usage patterns and failure rates do not vary greatly over time or from terminal to terminal, but that the distribution of probable causes of user problems varies significantly from terminal to terminal

    Abstract
    Desicusses the user training programme of the Helsinki University of Technology Library in the light of an internordic monitoring project. In the project, the use of OPACs was evaluated by analyzing the transaction logs and it was concluded that end users do not exploit the various possibilities of OPACs. A large part of the material found in the collections in the library is not retrieved: misspellings, lack of truncation, inequate use of Boolean operators and wrong database choices lead to ineffective retrieval. Emphasis in the online catalogue training has been on the 'hands on' exercises and it appears that the training programme is not very effective in the area of subject searching. Presents reasons for this and discusses plans for the future development of the library user training programme

    Abstract
    Reports results of the work of the Transaction Logs Task Force, composed of public and technical services librarians charged with reviewing OPAC to identify library wide problems and issues. This OPAC transaction log analysis study compared data derived from 2 sets of logs within a 6 month period. Analysis of the first set of data revealed that users experienced difficulty with basic searching techniques. The OPAC introductory screens were simplified and clarified to help users improve search success rates. The second set of data, analyzed after screen changes had been made, showed statistically significant differences in search results. Concludes that regular monitoring of OPACs through transaction log analysis can lead to improved retrieval when changes are made in response to an analysis of user search patterns

    Abstract
    Three studies were made of the use of COM catalogues at the University of Toronto and the Mississauga Library System: unobtrusive observations, structured interviews, and a timed-search experiment in reel, fiche and card catalogues. The reel catalogue was found to be the overwhelming favourite, almost as popular in the public library as in the academic library, where 82% of the users reported it to be their preferred form of catalogue. However, for nearly all test questions and searcher types in the timed-search experiment, successful searches required less time in the card catalogue than in either form of the COM catalogues.

    Abstract
    Describes a project which monitored electronically 11 public access terminals, at the Colorado University Librarys, to produce transaction logs that were used to gather statistics and analyze the behaviour of users when searching the library online catalogues. The study recorded user behaviour unobtrusively and focused exclusively on what actually occured during the search process. Among other findings it was revealed that the use of system supplied search aids varied, from low use of quick search and express search features, to more extensive use of search history and searching databases other than the home catalogue. Analysis of search results revealed that 66% of subject (keyword) and name searches produce 10 or fewer results, and 82% produce 25 or fewer titles, a manageable number for searchers to scan postings and spot relevant materials. User persistence in scanning titles was found to be high with the full list being requested for nearly 40% of searches netting up to 100 results. Overall, results show that emphasis on improved system design must be stressed if the needs of the majority of searchers are to be met more effectively

    Abstract
    Reports results of a questionnaire study to identify factors that affect diffusion of usage of online end user literature searching. 15 factors clustered into 3 attribute sets (innovation attributes, organizational attributes, and marketing attributes) were measured to study their effect on the diffusion of online searching within institutions. A random sample of 67 academic health sciences centres was selected and 1335 library and informatics staff members at those institutions were surveyed by mail with electronic mail follow up. Multiple regression analysis was performed. 2 dependent variables: internal diffusion (spread of diffusion); and infusion (depth of diffusion), were measured. There was little correlation between them, indicating they measured different things. 15 independent variables clustered into 3 attribute sets were measured. The innovation attributes set was significant for both internal diffusion and infusion and significant individual variables were visibility for internal diffusion and image enhancement effects (negative relation) as well as visibility for infusion (depth of diffusion). Organizational attributes were also significant predictors for both dependent variables. No individual variables were significant for internal diffusion. Marketing attributes were not significant predictors. Concludes that successful diffusion of online searching is dependent on the visibility of the systems, communication among, rewards to, and peers of possible users who promote use (champions)

    Abstract
    Describes an attempt, by Illinois University at Chicago (IUC) Library to respond to user needs as they are revealed in transaction logs of OPAC use. Illustrates success in improving access to catalogue records through a reengineering process. Outlines the IUC Library Reengineering Project, the administrative structure to study transaction logs, and the resultant managerial decisions. Notes the changes made to sreen display and to the OPAC. Focusing on customer satisfaction, IUC catalogue librarians joined forces with colleagues to identify Usrs' unmet needs and preferences through transaction log analysis. In order to minimize mismatches between users' expectations and services actually provided, IUC catalogue librarians studied logs and adjusted the OPAC. Descrinbes the specific efforts to increase access to the library's collections and the steps taken to enhance and customize bibliographic and authority records. Concludes that transition log analysis has enabled IUC to alter the form and content of its OPAC to fit the changing needs of diverse and widely disoersed users

    Abstract
    Reports an examination of the results of 114 sessions on the online catalogue, at the Ellis Library, Missouri University at Columbia, to determine what types of searches were conducted and what search modes and fields (title, author) were used. Examination of tranaction logs revealed that title and author searches predominated and that the opportunity to construct Boolean searches was rarely taken advantage of. The searchers themselves reported that they were, on the whole, experienced at using the system; most searched the catalogue at least once a week. This is reflected in the relatively low instance of error and in the fact that most searches produced at least some hits. The majority of errors that were made in the process of searching were typographical

    Abstract
    End users at Univ. of Southern California (USC) have free access to the last 10 years of MEDLINE via local online system known as USCInfo. Librarians at USC Norris Medical Library provide documentation and offer formal and informal training on the use of the system to search MEDLINE. To assess the educational needs of the end users, 643 searches were analysed. Although a high proportion (84%) of the searches were judged to be successful, the use of MeSH to obtain optimal results was low; only 20% of all successful subject searches employed MeSH. In addition, the advanced features of MEDLINE were underutilized. While it is promising to learn that many end users are obtaining positive results, methods which will encourage end users to improve their retrieval need to be developed

    Abstract
    The paper presents the results of a study on usability methods for evaluating Web sites. It summarizes the "Heuristics for Web Communications," and reports the practical experiences with these heuristics, contrasting them with the "Keevil Index" and combining them with user testing with thinking aloud. It concludes that working with the "Heuristics for Web Communications" takes more time and effort than working with the "Keevil Index," but produces more consistent results. The heuristics proved to be applicable both in heuristic evaluation and in combination with user testing.
