从文献计量学到网络计量学 总被引：1，自引：0，他引：1
从1958年以来,不知不觉中文献计量学已经发生了根本的变化:它独立成为一个学科,在图书馆和信息科学学院中被广泛教授,并成为世界各地科学评价研究组的核心研究内容。这些都因为尤金.加菲尔德的研究成果和他的科学引文索引而变得可能。本文回顾了文献计量学从1958年到现在的发展历程,对比了早期的文献计量学和它的当前研究内容,综述了一大批最新的研究方向和进展。比如专利分析、国家科研评价实践、新型可视化技术、创新应用、新在线引文索引以及数字图书馆创建相关的发展过程等。还对网络计量学,一门现代迅速发展的文献计量学的分支进行详细的评述。最后,对文献计量学和网络计量学的未来发展趋势也进行了探讨。 相似文献

选择期刊Scientometrics、Journal of Informetrics 2003-2012年期间发表的论文和国际科学计量学与信息计量学大会(ISSI大会)论文集论文为样本,对中国大陆和台湾地区科学计量学与信息计量学的发展进行比较研究。研究从4个方面展开:论文计量分析、引文计量分析、合作研究以及研究内容考察。研究结果表明,中国大陆和台湾地区已经成为国际上科学计量学与信息计量学论文产出大户,但是中国大陆地区论文年篇均引文略低于世界平均水平,AR指数低于台湾地区;两地区学者已经产出合著论文,但合作局限于少数学者和少数机构之间;两地区的研究对象和研究方法有共性又各有特色,中国大陆地区学者更重视科学计量,台湾地区学者更重视技术测度。最后提出促进两地区科学计量学与信息计量学发展需要深入讨论的几个问题。 相似文献

ABSTRACT The article examines the most important periodicals of ethnic minorities in Poland. After 1989, many ethnic groups (e.g., Germans and Romanies) were allowed to publish journals and newspapers for the first time since the end of World War II. The publications examined show the rich cultural life of the various ethnic groups as well as their current status in Poland. In addition to popular titles, some scholarly publications are also discussed. 相似文献

The author answers a reference question on bibliographic sources for the Ukrainian periodical press 1840–1850. Helpful publications include bibliographies, guides, and library catalogs. These potentially make mention of revolutionary developments in Hungary (such as the Twelve Points paragraph of the Demands of the Hungarian Nation in March 1848, the subsequent April Laws, and Hungary's declaration of independence in April 1949), and elsewhere in the Hapsburg Empire. 相似文献

Most studies of collection development mask inadequate theoretical underpinnings with facile assumptions and dazzling statistical manipulations. This essay, in moving toward a model for collection development within both specific collections and library systems as a whole, seeks to demonstrate the full range and complexity of relevant factors. An enlarged theoretical grasp should help highlight both the possibilities and the challenges of existing approaches. One result could be a shift toward gaming or simulation techniques as more realistic analytical tools. 相似文献

An annotated list is presented describing seventeen periodicals that cover significant aspects of the gay, lesbian, bisexual, and transgender (GLBT) community and their culture in whole or in part, with popular content rather than an academic or research focus. The titles included are a selective and representative sampling. The entry for each periodical includes the following information: periodical title, publisher/editor and address, basic information, publication data, content, Internet information, an abstract/annotation, and evaluative statement 相似文献

SUMMARY Ariel files are the starting point for electronic delivery of interlibrary loan articles through ILLiad, Virginia Tech's interlibrary loan system. Despite some advantages to electronic delivery of articles to their desktops, a large majority of ILL customers continue to prefer print on paper delivery rather than electronic delivery. This fact has implications for introducing additional electronic services. Correctly choosing what services to impose on library customers, and what services to offer as value-added options, is fundamental to maintaining the credibility of libraries during these times of rapid change. 相似文献

Library Journal's 2011 Ebook Penetration and Use in U.S. Libraries Survey testifies to e-books’ increasing popularity in academic libraries. This review tracked literature published from 2005 that focused on academic librarians’ best practices for acquiring, cataloging, maintaining, and promoting e-books at their institutions. Some of these practices include implementing trial accesses, considering institutional requirements, providing an e-book presence in the library catalog, monitoring usage statistics, and utilizing the library Web site for promotional efforts. 相似文献

SUMMARY There are between fifteen and twenty U.S. libraries that collect publications from Central Asia, defined here as Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. Collection development responsibility for these countries tends to rest with the Slavic selector, the Middle East selector, or both, divided by language. Vendors who can supply this material mostly also supply publications from other countries of the former Soviet Union. The author briefly discusses the history of collecting from this region and the results of a survey conducted in 2004. She presents evidence indicating that the main reason U.S. libraries are not receiving more books from the region is most likely because they are not being published, not because vendors are doing an inadequate job. 相似文献
