谷歌数字图书馆的迅速崛起对图书业生存提出了挑战。谷歌图书馆具有强大的服务功能、免费的服务方式、工业化的生产渠道优势,但缺少内容新鲜的全文图书,无法提供深度服务,信息查全率不高。图书馆发展要发挥传统阅读的优势,探索新的服务模式,加大投资制作特色音视频数据库,发挥实体图书馆的功能,解开著作权的死结。 相似文献

About 113 million Americans have reported seeking health information online; however, little is known about the quality (or qualities) of the information being retrieved. Users have reported seeking information about health issues in an attempt to reduce negatively appraised uncertainties (Brashers, 2007), but less is known about the ability of the retrieved information to increase or produce unwanted uncertainty. A content analysis of online cancer news was conducted and suggests that 65% of Internet-based cancer news contains message features previously linked to the production of uncertainty (e.g., ambiguous or complex information). Though future research is required regarding uncertainty-related content and its effects, this project provides a foundation for such future endeavors. 相似文献

ABSTRACT. Google is pursuing “mass digitization” of Russian books as part of its efforts that now involve more than a dozen partners, although so far there is no separate Russian‐language search interface. How easy is it to find materials in books.google.com that are in Russian? What do users need to know to maximize their results? 相似文献

This investigation sought to develop a broad view of discovery service user behavior by analyzing vendor-provided and Google Analytics usage data from discovery service implementations at two Indiana University campuses. The results of this analysis demonstrate how usage data can communicate both intermediary and end results of user interactions within discovery services. The findings reveal user behavior trends, which may be used to develop strategies to improve information literacy instruction techniques, as well as discovery service interface enhancements. 相似文献

This article presents the results of a comparative study of Web of Science (WoS), Scopus, and Google Scholar (GS) for a set of 15 business and economics journals. Citations from the three sources were analyzed to determine whether one source is better than another, or whether a new database such as Scopus, or a free database such as GS could replace WoS. The authors concluded that scholars might want to use alternative tools collectively to get a more complete picture of the scholarly impact of an article. 相似文献

This article summarizes published documents on metadata provided by Google for books scanned as part of the Google Book Search (GBS) project and provides suggestions for improvement. The faulty, misleading, and confusing metadata in current Google records can pose potentially serious problems for users of GBS. Google admits that it took data, which proved to be inaccurate, from many sources and is attempting to correct errors. Some argue that metadata is not needed with keyword searching; but optical character recognition (OCR) errors, synonym control, and materials in foreign languages make reliable metadata a requirement for academic researchers. The authors recommend that users should be able to submit error reports to Google to correct faulty metadata. 相似文献

The University of New Mexico (UNM) has used the Google Search Appliance (GSA) to provide search for the University's Web content. When the GSA license expired, the campus Information Technologies (IT) department and the University Libraries (UL) took the opportunity to collaborate on a re-launch of the service as a joint project. By collaborating closely with IT, the UL personnel gained insight and first-hand information on how to optimize the Libraries’ Web presence. Outcomes were positive, both in the resulting product and in building bridges between the work cultures. 相似文献
