Finding and Evaluating Health Sources on the Internet

Summary

Librarians and patrons searching for reliable health information are fortunate in that this subject area is one for which many reliable, in-depth sites exist. Government, education, and organization sites are, in particular, good sources of information and provide links to other Web pages. It is important, however, for both librarians and their clients to know how to access this information and, especially, how to evaluate the worthiness and usefulness of the information contained therein.

Cataloging Databases and Web Sites in OCLC and Voyager

Use of dynamic links from subject-based finding aids to records for electronic resources in the OPAC is suggested as one method for by-passing the OPAC search interface, thus making the library's electronic resources more accessible. This method simplifies maintenance of links to electronic resources and aids instruction by providing a single, consistent access point to them. Results of a usage study from before and after this project was completed show a consistent, often dramatic increase in use of the library's electronic resources.

Extensions to the STAIRS Study—Empirical Evidence for the Hypothesised Ineffectiveness of Boolean Queries in Large Full-Text Databases

The STAIRS study conducted by Blair and Maron in the mid-80's is a milestone in the history of IR evaluation. Blair and Maron made strong conclusion about the inadequacy of free-text searching large databases, and their study has been widely referred in the literature to justify the problems of effectiveness in IR systems. However, some critics of the study have plausibly pointed out that the ineffectiveness conclusions were not solidly based on empirical data.This paper introduces a new theoretical and empirical approach to study the problems of high recall searching in large databases and reports the results of a case experiment. The findings verify some of the hypothetical conclusions introduced in the STAIRS study, and expands the picture of falling performance. It is shown that low precision in high recall searching is unavoidable in exact-match Boolean searching since even major concepts are often expressed implicitly in relevant documents. The author suggests that the problem could be reduced in facet-based best-match searching.     

Books Effectively Censored: Discrimination at a University Library: Alumni the Target

Abstract

This article presents the results of a study performed on the interlibrary loan patron request records at the library of John Jay College of Criminal Justice, an urban commuter college with a specialized curriculum. The findings suggest that the increasing availability of electronic full-text resources has had a significant impact on the volume of faculty and graduate student interlibrary loan borrowing of nonreturnable, photocopied materials. This appears to be the case across disciplines and regardless of the currency of the needed materials. The downward trend in demand for these materials may be outpacing actual full-text availability. This may suggest that content is being replaced with convenience. This could have implications for reference librarians and their role in the research process. Declining demand may also provide interlibrary loan librarians and their staff opportunities to alter their services and develop new skills.

Internet Reference Sources in Education

Summary

With so many Internet sites devoted to education for educators, administrators, and librarians, it can be a daunting experience trying to find needed resources. There are special sites devoted to teachers, children, and parents. The government provides free access to database searching, statistics, and full-text publications. State and local levels of government also host valuable data and reports. More and more journals are appearing online in full-text format escalating user expectation to assume all journals will be available via the Internet. Tapping into higher education and academic library sites connects to content rich links. While this is not an exhaustive listing of educational Web sites, it leads to a myriad of valuable resources.

Pakistani University Library Web Sites: Features,Contents, and Maintenance Issues

ABSTRACT

This study explores the current status and features of Pakistan's academic library Web sites. A checklist describing features and content was prepared based on a review of the literature related to academic libraries’ Web sites. Then, all 85 library Web sites of Pakistani universities and degree-awarding institutions recognized by the Higher Education Commission (HEC) of Pakistan were surveyed and analyzed using the checklist. Interviews with library professionals were conducted to learn more about the problems and issues with building and maintaining library Web sites. Results indicate that Pakistani academic library Web sites have effective features such as contrasting color schemes, easily readable text, minimal use of horizontal scrolling, and English-language text. Staff information, OPACs, and navigation features are also widely found on the Web sites. Features found less frequently include the use of Web 2.0 technologies, Web site aid tools, information about library buildings, and general library information. By offering information about the status of Pakistani academic library Web sites, the study can serve as a foundation for discussion between libraries and other parts of the university, as well as a benchmark for evaluating the progress of academic library Web sites in Pakistan
