《Government Information Quarterly》1997,14(4):373-395
The number of federal agencies creating and maintaining electronic networked resources continues to increase. One networked resource federal agencies are increasingly using is the World Wide Web (Web). As government use of the Web rises, so too does the need for assessing the extent and nature of public use of agency Web sites. One means of Web use evaluation is through the analysis of Web server-generated log files. This article presents various log file analysis techniques and issues related to the interpretation of log file data. 相似文献

Chinese academic libraries have been devoting great effort into introducing next-generation online public access catalogs (OPACs) in order to provide a better user experience. However, there is a lack of empirical research on their usage. In this study, a transaction log file from a typical next-generation OPAC, the Wuhan University Library OPAC, formed the basis for an investigation of users' information behavior, using a clickstream data analysis framework. The 26,732,368 clickstream records in the original log file were cleaned, parsed, coded, then analyzed at the footprint, movement, and pathway levels. The results showed that the users relied heavily on the single-box simple search interface, seldom involved themselves in an exploratory search process, and preferred page navigation over search refinement when interacting with search results. The OPAC was used as a lookup tool to locate known academic resources and as a personal information management tool to utilize basic library services, instead of as a discovery tool as intended. 相似文献

The following study analyzes user search behavior using a tabbed-search interface. For this study, a transaction log was used to collect information about user searches and included tab used; search terms; date, time, and location of search (on campus or off campus); as well as a unique ID to identify the user session and another ID to identify each transaction. This article explains the process for examining 4,300 search queries conducted on the library homepage during an academic semester and presents findings from the analysis. The article also details enhancements that were made to the tabbed-search interface as a result of the transaction log analysis. Additionally, the article discusses the merits of using a transaction log as a method of ongoing assessment of a library Web site's search interface. 相似文献

Measuring in-library use of printed journals has always been difficult. Even when libraries monitor the use of their journal collections, data collected rarely go beyond the level of title and are often incomplete. Participation in a European Union funded project on the delivery of electronic files of journals to end users (DECOMATE) has enabled the London School of Economics (LSE) to collect qualitative and quantitative data on the use of its journal collections. This paper describes how user statistics are being collected at the LSE. It looks at the difficulties that have been encountered in collecting the data and at the solutions that have been found. Comparisons will be made between patterns of use within a traditional library environment and user behavior as journal literature becomes available as electronic images, accessible over the network. The paper concludes with speculation about the benefits that may derive from collecting and analyzing user statistics. 相似文献

The Central Medical Library (CMK) at the Faculty of Medicine, University of Ljubljana, Slovenia, started to build a library Website that included a guide to library services and resources in 1997. The evaluation of Website usage plays an important role in its maintenance and development. Analyzing and exploring regularities in the visitors'' behavior can be used to enhance the quality and facilitate delivery of information services, identify visitors'' interests, and improve the server''s performance. The analysis of the CMK Website users'' navigational behavior was carried out by analyzing the Web server log files. These files contained information on all user accesses to the Website and provided a great opportunity to learn more about the behavior of visitors to the Website. The majority of the available tools for Web log file analysis provide a predefined set of reports showing the access count and the transferred bytes grouped along several dimensions. In addition to the reports mentioned above, the authors wanted to be able to perform interactive exploration and ad hoc analysis and discover trends in a user-friendly way. Because of that, we developed our own solution for exploring and analyzing the Web logs based on data warehousing and online analytical processing technologies. The analytical solution we developed proved successful, so it may find further application in the field of Web log file analysis. We will apply the findings of the analysis to restructuring the CMK Website. 相似文献

Objectives:
The purposes of this study were: to determine the number of articles requested by library users that could be retrieved from the library''s collection using the library catalog and link resolver, in other words, the availability rate; and to identify the nature and frequency of problems encountered in this process, so that the problems could be addressed and access to full-text articles could be improved.Methods:
A sample of 414 requested articles was identified via link resolver log files. Library staff attempted to retrieve these articles using the library catalog and link resolver and documented access problems.Results:
Staff were able to retrieve electronic full text for 310 articles using the catalog. An additional 21 articles were available in print, for an overall availability rate of nearly 80%. Only 68% (280) of articles could be retrieved electronically via the link resolver. The biggest barriers to access in both instances were lack of holdings and incomplete coverage. The most common problem encountered when retrieving articles via the link resolver was incomplete or inaccurate metadata.Conclusion:
An availability study is a useful tool for measuring the quality of electronic access provided by a library and identifying and quantifying barriers to access.Highlights
- Lack of holdings, including access to recent articles restricted by embargoes, was the most common barrier to locating full text, accounting for over 90% of all identified problems.
- Availability rates for electronic articles varied by year of publication and by the database in which the OpenURL request originated.
- Link resolver error rates varied widely based on the source of the request and frequently resulted from incomplete or inaccurate metadata.
Implications
- An availability study is an inexpensive, practical tool for assessing the quality of electronic access to journal articles.
- The results of an availability study can help libraries identify barriers to access and thereby allocate limited resources to areas that will provide the most benefit to users.
- Link resolvers might be more accurate if the quality of metadata in OpenURLs was improved and the behavior of full-text targets was standardized.
- Collection and acquisition problems: The library may not subscribe to the desired journal, or the article and/or journal may be unavailable for some other reason.
- Cataloging and holdings problems: The journal may be cataloged or indexed incorrectly, or the library''s holdings data may be wrong.
- Technical problems: Problems may occur with the journal provider''s site or the library''s proxy server.
- gather actual user requests (or simulate them)
- try to fill those requests using the same tools and methods a user would use
- record what happens
- analyze the results

Purpose: To begin investigating the impact of electronic journals on research processes such as information seeking, the authors conducted a pilot journal-use study to test the hypothesis that patrons use print and electronic journals differently.Methodology: We placed fifteen high-use print titles also available in electronic format behind the circulation desk; patrons were asked to complete a survey upon requesting a journal. We also conducted a parallel survey of patrons using library computers. Both surveys asked patrons to identify themselves by user category and queried them about their journal use.Results: During the month-long study, patrons completed sixty-nine surveys of electronic and ninety surveys of print journal use. Results analysis indicated that fellows, students, and residents preferred electronic journals, and faculty preferred print journals. Patrons used print journals for reading articles and scanning contents; they employed electronic journals for printing articles and checking references. Users considered electronic journals easier to access and search than print journals; however, they reported that print journals had higher quality text and figures.Discussion/Conclusion: This study is an introductory step in examining how electronic journals affect research processes. Our data revealed that there were distinct preferences in format among categories. In addition to collection management implications for libraries, these data also have implications for publishers and educators; current electronic formats do not facilitate all types of uses and thus may be changing learning patterns as well. 相似文献

Abstract This paper describes a grant-funded research project to relocate selected print journal runs, for which an electronic version is available, to remote storage from the shelves of campus libraries at the University of California. During the project, users will rely on the electronic version of selected journals. Data, including costs associated with the project, usage of print journals, usage of electronic journals, as well as user behavior and attitudes, will be gathered and used to develop long-range strategies and institutional policies. 相似文献

Abstract Using the BUBL Journals service as a rich source of data, this article outlines different methods of measuring usage of electronic journals, suggests that different types of access may be mapped to the user activities of browsing, reading and searching, and draws some inferences about why different titles have differing patterns of usage. It also proposes that by measuring the ‘search-to-browse’ ratio of a journal it is possible to assess whether journals are being used primarily for research and reference purposes or mainly for current awareness and casual browsing. 相似文献

PURPOSE: Identify journal collection access and use factors. SETTING AND SUBJECTS: University of North Carolina at Chapel Hill's Health Sciences Library patrons. METHODOLOGY: Survey forms and user interactions were monitored once a week for twelve weeks during the fall 1997 semester. The project was based on a 1989 New Mexico State University study and used Kantor's Branching Analysis to measure responses. RESULT: 80% of reported sought journal articles were found successfully. Along with journal usage data, the library obtained demographic and behavioral information. DISCUSSION AND CONCLUSIONS: Journals are the library's most used resource and, even as more electronic journals are offered, print journals continue to make up the majority of the collection. Several factors highlighted the need to study journal availability. User groups indicated that finding journals was problematic, and internal statistics showed people requesting interlibrary loans for owned items. The study looked at success rates, time, and ease of finding journals. A variety of reasons contributed to not finding journals. While overall user reports indicated relatively high success rate and satisfaction, there were problems to be addressed. As the library proceeds in redesigning both the physical space and electronic presence, the collected data have provided valuable direction. 相似文献

This article examines the complicated process of journal title transfers in the electronic environment. A detailed look at summary title transfer data from the past two years outlines the untimely nature of the title transfer process. Also addressed are how two National Information Standards Organization (NISO)/United Kingdom Serials Group (UKSG) Working Groups, Knowledge Bases and Related Tools (KBART) and Transfer, are working to address some of the problems and streamline the process. Last, an automated and standardized method by which electronic holdings data could be processed is proposed for future work. 相似文献

With the advent of e-journal preservation projects and publisher digitization of journal backfiles, academic libraries have begun to move their corresponding print volumes of these titles to storage to avoid duplication and save space. This article examines the supporting justifications, outreach mechanisms, and logistical procedures undertaken at American University Library to relocate the entire bound journal collection to offsite storage in order to address severe physical space constraints and to support patron use of and preference for electronic journal content. In addition, the article presents preliminary data regarding the use of bound volumes sent to storage and an overall analysis of this transformational project. 相似文献
