数字对象唯一标志符DOI(digital object identifier),已成为云计算平台上电子文献样本存储和按需服务的最佳应用技术。本文介绍了DOI的发展历史与国际现状,分析了大数据时代期刊DOI的存在意义,特别是2009年JCR新增了eigenfactor score和article influence score 2个评价指标后,DOI已成为评价指标的唯一依据。对2013年300种高校期刊进行了分析,发现其DOI应用比例严重偏低,仅占17.6%,原因有3点:1)期刊无独立网站和过刊回溯功能;2)申请了DOI,但没有针对期刊的文章信息进行注册或在文章上注明DOI;3)期刊网站改版或者网络链接(URL)的变更,没有及时重新注册DOI元数据。建议我国期刊建立数字化平台网站或与国内外大型出版集团合作,在拥有DOI号的同时,同步进行注册,使其成为期刊数字出版的"利器",为广大受众服务,使国内与国外数字出版同步发展。 相似文献

Between 1929 and 2002 over 200 English‐language scientific journals were founded in China. The number of China's English edition journals in each discipline is, however, not correlated to the corresponding output of China's articles listed in the ISI's Science Citation Index. Clearly, the goal of these journals is to be internationally recognized. It is shown that this goal is rarely achieved. We think that lack of good‐quality papers, low international visibility and a citation ‘Matthew effect’ are the main causes for the small role played by China's English‐language journals. 相似文献

Although there are at least six dimensions of journal quality, Beall's List identifies predatory Open Access journals based almost entirely on their adherence to procedural norms. The journals identified as predatory by one standard may be regarded as legitimate by other standards. This study examines the scholarly impact of the 58 accounting journals on Beall's List, calculating citations per article and estimating CiteScore percentile using Google Scholar data for more than 13,000 articles published from 2015 through 2018. Most Beall's List accounting journals have only modest citation impact, with an average estimated CiteScore in the 11th percentile among Scopus accounting journals. Some have a substantially greater impact, however. Six journals have estimated CiteScores at or above the 25th percentile, and two have scores at or above the 30th percentile. Moreover, there is considerable variation in citation impact among the articles within each journal, and high-impact articles (cited up to several hundred times) have appeared even in some of the Beall's List accounting journals with low citation rates. Further research is needed to determine how well the citing journals are integrated into the disciplinary citation network—whether the citing journals are themselves reputable or not. 相似文献

There are enormous quantities of information available to researchers on the Internet, of varying levels of quality. Now, more than ever, it is important that academic publishers make best use of their journals and provide their readers with access to this high‐value content, in a form that can be easily found and used. To that end, Taylor & Francis have taken up the challenge of satisfying researchers' need to have all relevant content available at their fingertips, by digitizing their older journal content, creating subject‐based collections of backfiles and putting them online. This article provides an insight into the ‘why’ and ‘how’ of the process of digitization of Taylor & Francis's journal archives. The fact that these online backfiles are being requested, purchased, and used demonstrates the added value that publishers may hold in their archives. 相似文献

The early days of the People's Republic of China saw the development of science and technology at home with an accompanying development of scientific and technical journals. A succession of natural disasters then weakened the economy and many journals had to cease publication. The disruption of the Great Proletarian Cultural Revolution followed and only twenty journals survived. Since the opening up of the economy the Chinese government has supported scientific and technical journals and these have developed rapidly. There are now a large number of journals but many of them are still of low quality and little impact, and too few are in English. The number in English will now increase considerably, as will their international influence. 相似文献

Abstract The purpose of this article is to outline the “best common practices” at Regent University Library, and share survey data illustrating their effectiveness. Also discussed is how transitioning from an entirely graduate university to a university serving both graduates and undergraduates has influenced library services. The new constituency will increase interlibrary loan transactions and test the library's practices. Providing quality interlibrary loan service to a growing academic population requires innovative ideas and practices while keeping the workflow streamlined. New programs implemented over the past several years include books on demand and providing more electronic books and journals. A growing distance education student population has led to paying for library cards for academic libraries located near students' homes and permitting them to return materials to satellite campuses. 相似文献

A comparison of a Bradford-ranked list of journals in the field of mathematics with a list of the same journals ranked by citation counts finds little correlation between the two. A previous study by Lamb shows a high correlation between a ranking based on citation frequency for these journals and a ranking based on the prestige of individual contributors. Lamb's study suggests that a selection policy based on choosing journals publishing the most papers on a topic will result in the acquisition of high quality papers. The results of this study cast doubt on Lamb's conclusions. 相似文献

In this article, the author discusses the creation of an electronic index of scholarly Slavic periodicals in the humanities, which will launch in early 2012. The aim of this project is to create a standard electronic reference tool in the field of Central, Eastern, and Southeastern European Studies, which will help professors, students, and researchers. The index contains important scholarly journals from Belarus, Bulgaria, Croatia, the Czech Republic, Macedonia, Poland, Serbia, Slovakia, Slovenia, and Ukraine. Indexing begins with 1994 issues and is ongoing. In the future, significant retrospective journals will be indexed in order to improve the tool's research capabilities. The index contains not only articles, but also all book reviews and information on conferences, workshops, organizations, and foundations. The index currently contains citations of over 125,000 articles from more than 143 Slavic journals in the humanities. The use of the Library of Congress transliteration scheme and subject headings will assist users to perform effective searches. 相似文献

This study examines year-by-year correlations between Freedom House and Reporters Sans Frontières' (RSF) press freedom scores for countries over a 13-year period (2002–2014). The goal of the study is to test the hypothesis that, further into the age of digital disclosure, as press abuses and harassment of journalists are more widely reported, press freedom ranking systems are gradually becoming more precise and, therefore, correlations between the two indices will strengthen over time. To further assess concurrent validity of the indices, correlations between both indices and scores on the United Nations Human Development Index are also provided. The study also examines changes in the indices' rankings of countries over time within six world regions: the Middle East and North Africa, the Americas, Western Europe, Eastern Europe/Central Asia, Sub-Saharan Africa, and Asia. In so doing, this study adds a degree of understanding to the validity of two press freedom indices that are routinely cited in journalistic reportage and trade journals, as well as many scholarly publications. Results suggest that the two organizations' scoring of press freedom has become significantly more correlated in the years 2002–2014, and the primary cause of the increased agreement is that RSF's ratings became substantially more aligned with Freedom House's scores during this period. Both indices' ratings are significantly correlated with countries' United Nations Human Development Index scores. 相似文献

The problem of how to rank academic journals in the communication field (human interaction, mass communication, speech, and rhetoric) is one of practical importance to scholars, university administrators, and librarians, yet there is no methodology that covers the field's journals comprehensively and objectively. This article reports a new ranking methodology based in empirical criteria. The new system relates independent measures of the prestige of the field's doctoral departments to information about where faculty members from those departments have published scholarly articles. This new approach identifies the field's most influential journals as those that more frequently publish the work of the field's top scholars and programs as perceived by their peers. This system was used to compute prestige weights (P-weights) for 65 communication journals. P-weights were found to be strongly correlated with ISI Web of Science journal impact factor scores and can be used to identify an overall prestige hierarchy for communication journals as well as prestige rankings by subject specialty. 相似文献

This study examines how the social sciences' debate between qualitative and quantitative methods is reflected in the citation patterns of sociology journal articles. Citation analysis revealed that quantitative articles were more likely to cite journal articles than monographs, while qualitative articles were more likely to cite monographs than journals. Quantitative articles cited other articles from their own quantitative-dominated journals but virtually excluded citations to articles from qualitative journals, while qualitative articles cited articles from the quantitative-dominated journals as well as their own qualitative-specialized journals. Discussion and conclusions include this study's implications for library collection development. 相似文献

This paper explores a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal's contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field's literature. It further develops Eugene Garfield's notions of a field's ‘citation potential’ defined as the average length of references lists in a field and determining the probability of being cited, and the need in fair performance assessments to correct for differences between subject fields. A journal's subject field is defined as the set of papers citing that journal. SNIP is defined as the ratio of the journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields. Citation potential is shown to vary not only between journal subject categories – groupings of journals sharing a research field – or disciplines (e.g., journals in mathematics, engineering and social sciences tend to have lower values than titles in life sciences), but also between journals within the same subject category. For instance, basic journals tend to show higher citation potentials than applied or clinical journals, and journals covering emerging topics higher than periodicals in classical subjects or more general journals. SNIP corrects for such differences. Its strengths and limitations are critically discussed, and suggestions are made for further research. All empirical results are derived from Elsevier's Scopus. 相似文献

Recently, there has been an alarming increase in the number of “academic” papers published in vanity journals and publishers. Such journals, dubbed predatory because their main objective is making money out of authors, compromise or completely abandon the peer review system. An increase in publishing with such journals, which is common in developing counties, will affect the quality of science, excellence, development, and individual researchers' and institutions' professional reputation. In this article, the author discusses strategies for individual researchers and institutions for identifying and discouraging publishing in predatory journals. Moreover, suggestions on how to deal with faculty who have published and already bestowed positions on the grounds of papers published in predatory journals are also given. Strategies and suggestions discussed in this article can provide insights to librarians and publication officers on how to curb the problem of predatory publications. 相似文献

This paper describes how the library at BT Labs is working on building a digital library of technical information for its users. The paper will explain how the library changed its direction from providing conventional library services centered around a large library collection toward becoming a networked library reaching out to its users' desktops. In particular, the paper will focus on the process by which electronic journals were added to the collection and how they have been integrated into the digital library. 相似文献

TACOS is an acronym for TAble of COntents Service. It provides recipients with photocopies of the contents pages of journals selected from the hospital's list of serials. The service enables users to augment their journals by scanning additional tables of contents. TACOS coexists with and complements computer, SDI and other current awareness services. Growth over a five-year period is evident by an increased number of both TACOS requesters and TACOS journals requested. User satisfaction, as measured by a survey and willingness to pay, is high. TACOS is a simple, viable concept well worth implementing even in times of tight budgetary constraints. 相似文献
