通过对2007—2010年ScienceDirect数据库和中国期刊全文数据库的下载数据统计分析可知,两个期刊全文数据库中均存在帕累托效应,非母语文献期刊全文数据库表现出的帕累托效应更为明显,专业特色强的学校期刊全文数据库表现出的帕累托效应比综合性学校更为明显。期刊全文数据库中的帕累托效应有助于图书馆确定核心期刊,订购纸本期刊和电子期刊,优化区域联盟采购,有助于图书馆与院系划分经费分摊比例,发现参考咨询服务和读者培训的重点。 相似文献

外文期刊全文数据库可以补充和代替部分印刷型期刊的馆藏，因此对外文期刊全文数据库来源期刊的比较及评价方法研究的重要性日益增强。将外文期刊全文数据库的全文来源期刊和文摘来源期刊列表与特定馆藏相比较，从而确定一些参数（全文期刊值、文摘值、CAR和馆际互借值），准确评价数据库的全文来源期刊和文摘来源期刊，最终根据不同图书馆的馆藏、规模和需求确定外文期刊全文数据库的订购方案将是当前各类型图书馆的最佳选择. 相似文献

Journal articles are often made available prior to assignment to an issue, using labels like “early view,” “advanced online publication,” “ahead of print,” “online first,” or “in press.” While making articles available before an issue can speed up the scholarly communications cycle, a negative effect can be observed when full text is delivered through aggregator databases like EBSCO, ProQuest, or Gale products. This study assessed issue assignment delays across 18 journals which have full text aggregated in EBSCO's CINAHL Ultimate. Results show that articles published first in an early-view state are only available in the aggregator after they have been assigned to an issue. Any database-specific full-text delays (“embargos”) are then calculated from issue date rather than online publication date, leading subscribers who access the journals via aggregators to experience extended delays ranging from months to years in length. 相似文献

As end-user demand for easy access to electronic full text continues to climb, an increasing number of information providers are combining that access with their other products and services, making navigating their Web sites by librarians seeking information on a given product or service more daunting than ever. One such provider of a complex array of products and services is Thomson Scientific. This paper looks at some of the many products and tools available from two of Thomson Scientific's businesses, Thomson ISI and Thomson ResearchSoft. Among the items of most interest to health sciences and veterinary librarians and their users are the variety of databases available via the ISI Web of Knowledge platform and the information management products available from ResearchSoft. 相似文献

Many publishers of medical journals actively court coverage by the news media. However, the extent and effect of these practices are poorly understood. After reviewing prior literature regarding the impact of news coverage on the citation rate of journal articles, this paper seeks to measure the extent to which medical journals with clinical significance use public relations practices to encourage news coverage of their articles, and the success that those practices had in increasing coverage by newspapers. Editors of 120 medical journals published worldwide with clinical relevance were surveyed; the response rate was 54%. Eighty per cent of respondents reported that their journal offered journalists at least one of press releases, access to full‐text articles, or press conferences. Editors whose journals used the practices in conjunction with an embargo reported higher‐quality news coverage than editors of journals that did not, but editors and journalists held differing views about the justifications for the specific practice known as an embargo. 相似文献

Until recently, Croatian scientific journals were accessible only in print form and only to a relatively small audience. A national online journals platform was therefore planned to offer publishers a simple tool for building online versions of their journals and to make them open access. The platform, named Hr?ak, was launched in 2006, supported by governmental funds. It currently includes 170 open access (OA) journals. Most journals include backfiles from 2006 onwards; the average archived period is 6.3 years. 56.5% of the journals come from the fields of social sciences and humanities. Metadata from the Hr?ak platform are regularly harvested by OA repositories. To increase the number of Croatian journals covered by relevant bibliographic and full‐text databases, Hr?ak has forged links with Elsevier, Thomson Reuters and EBSCO. So far, the main achievements include assisting publishers in the process of electronic publishing, and improving accessibility to Croatian scientific output. 相似文献

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
