ABSTRACT Scopus is a new all-science abstracting and indexing (A&I) database. It is the result of a two-year collaboration with librarians and researchers from all over the world. Scopus covers over 14,000 scientific, technical, medical and social science titles from 4,000 publishers. It offers new sorting and refining features so that researchers can easily find and access more than 27 million abstracts and citations stretching back to the mid-1960s. This article recounts the development of Scopus from its inception in 2002 to its success in securing over 100 customers within weeks of its recent launch. The story is told by one of the librarians heavily involved in testing and shaping the product and by one of the Product Managers who built it. 相似文献

This article describes the experience in editing organization profiles in Scopus and in the Science Index for organizations system, which is an add-on to the Russian Science Citation Index (RSCI). The basic functionalities of the two systems are analyzed and comparison of the Science Index for organizations with the possibilities of editing an organization profile in Scopus is carried out. An attempt is made to give an objective assessment of the current state of the two systems from the user’s point of view. The conclusion is made that despite the more extensive functionalities of the Science Index for organizations, the feedback system in Scopus is well thought out and provides better control of changes that are requested by organizations. In the system of editing the profile of an organization in the RSCI the functional tools are characterized by a low level of moderation, which has a formal character; therefore, it can be used not only to edit a profile, but to create unreasonable increases in the values of bibliometric indicators. 相似文献

Comprehensive yet efficient search methods are essential for any systematic or scoping review. This article outlines the stages of development of a systematic search methodology for a scoping review within the library and information science (LIS) literature. The effectiveness of the database search strategies (LISTA, LISA, ERIC, Scopus, Web of Science) and supplemental search techniques are measured through a retrospective analysis of performance metrics. Findings show that for research topics limited to the library setting, it may be more effective to search fewer databases (LISTA and Scopus only) for peer reviewed journal articles and allot more time to alternate search techniques such as web searching to identify non-journal literature. The article provides an evidence-based, methodological approach to developing a systematic search plan, unique to LIS researchers, that accounts for time and resource needs. 相似文献

Many journals post accepted articles online before they are formally published in an issue. Early citation impact evidence for these articles could be helpful for timely research evaluation and to identify potentially important articles that quickly attract many citations. This article investigates whether Microsoft Academic can help with this task. For over 65,000 Scopus in-press articles from 2016 and 2017 across 26 fields, Microsoft Academic found 2–5 times as many citations as Scopus, depending on year and field. From manual checks of 1122 Microsoft Academic citations not found in Scopus, Microsoft Academic’s citation indexing was faster but not much wider than Scopus for journals. It achieved this by associating citations to preprints with their subsequent in-press versions and by extracting citations from in-press articles. In some fields its coverage of scholarly digital libraries, such as arXiv.org, was also an advantage. Thus, Microsoft Academic seems to be a more comprehensive automatic source of citation counts for in-press articles than Scopus. 相似文献

This article examines social science language trends in scholarly communication by looking at JSTOR and Scopus bibliographic data between 1996 and 2012. The results reveal that these two databases contain nearly 90 percent English-language publications. According to our analysis, Scopus continues to add more non-English peer-reviewed content while JSTOR totals are declining. To frame this discussion, the data are considered with reference to larger scholarly communication trends in the sciences, social sciences, and humanities. This study will be relevant for librarians who are interested in non-English scholarly publishing and collection development. 相似文献

Through the lens of political economy of communication and sports, this article examines the role of Bollywood’s sports movies in promoting patriotism and constructing an Indian national identity. Focusing on three popular movies premiered in the last decade, Dil Bole Hadippa (2009), Chak De! India (2007), and Lahore (2010), we explicate how Bollywood mobilized patriotic codes through these films in ways that are advantageous for the Indian government and the economic goals of the industry. 相似文献

在数字时代,公益性图书馆通过互联网络为社会公众提供数字资源是其发挥继续教育与终身教育职能的重要表现形式。在各类数字资源中,国家享有著作权的作品虽然在数量上未占主要部分,却举足轻重。长期以来,因政府执行不力、社会重视度不够等因素而远远未发挥其作用。文章从国家享有著作权作品的界定入手,首先分析了对其进行管理与利用的现状,随后探讨了加强对该部分资源利用的策略,具体包括国家相关法律与政策的出台或修订、加大政府经费投入、由各类大型公益性图书馆进行数据库加工后提供给全社会利用等。 相似文献

Objectives: In 2007, the Alberto Malliani Medical Library of the Università degli Studi in Milan decided to order some novels for its students. The library purchased 24 titles written by famous authors and planned to add others in the future. The proposal for this action was made by a professor, with whom the library had previously co‐operated in organising meetings for students. This article summarises the results of this experiment over 4 years, from its conception, to determine whether any positive outcome has resulted, including how library users welcomed this addition to the library and evaluation of its economic sustainability. Results: Data from July 2007 to December 2010 are presented in terms of the initial purchases, costs, and volume of lending for this section of the library; in addition, readers’ preferences are examined. Conclusions: A university medical library can act as a stimulus to its students’ new or renewed interest in literature, assuming that the novels, biographies, and short stories can contribute positively to the training of medical students. Therefore, setting up a special section can be useful, even though the costs of this section must be limited. A questionnaire could be the method of gathering information about users’ assessment. 相似文献

This article describes the process of transforming the Arkansas Periodical Index, which began as a card file index in the University of Arkansas (U. of A.) Libraries, to an online database. As in many other states, in-house indexes were compiled to cover local history journals and subject-related magazines. A variety of software now exists to mount locally created databases, one option being the choice to use the same turnkey software that runs the library's online catalog. We began by converting our card files to a local Inmagic DB/Textworks database. The U. of A. received the 1991 Gale Research Award for Excellence in Reference and Adult Library Services for that design. We later mapped the database structure to MARC fields and mounted it as a Web-accessible database through our library OPAC vendor, Innovative Interfaces, Inc. (III). The authors begin with a brief history of periodical indexing, the reasons for choosing MARC formatting, and the field mapping required. The article explains the development of the database to include other publication formats, such as material from biographical compendiums, newspaper indexing, and university publications. The mapping incorporates indexing several publication formats in the same database. It also provides fields for linking citations back to the OPAC records, where users may find call numbers for journals or books, be connected to the full text of articles when available, or to an association's own website when applicable. We address some of the concerns for libraries in developing indexing projects. The article offers a mapping table of migrated fields that can be used by others wanting to encourage the rediscovery of local print periodicals and to expand access to the various materials otherwise buried in the library's special collections. The Arkansas Publications Index was released in April 2005 and is available free at http://arkindex.uark.edu/. 相似文献

This article discusses the origins of Transborder Data Flows (TDFs) as an international problem in the early 1970s and the realization, among all concerned, that country-by-country control of such TDFs was likely to be problematic. The article shows how further technological development in telecommunications and networks in the intervening years has made regulation more complex but also more urgent. Part of this urgency emanates from increased danger of computer crimes such as copyright infringement, breach of personal privacy, and electronic sabotage. The problems being experienced by the U.S. government in responding, unilaterally, to this danger through the Key Escrowed Encryption System (KEES), popularly known as the clipper chip, illustrate the need for an international response. Such a response, is feasible in the 1990s due to the growth of multilateralism and the changing nature of national sovereignty. The article recommends the internationalization of the KEES and development of broad international TDF regulations and enforcement mechanisms. 相似文献

A size-independent indicator of journals’ scientific prestige, the SCImago Journal Rank (SJR) indicator, is proposed that ranks scholarly journals based on citation weighting schemes and eigenvector centrality. It is designed for use with complex and heterogeneous citation networks such as Scopus. Its computation method is described, and the results of its implementation on the Scopus 2007 dataset is compared with those of an ad hoc Journal Impact Factor, JIF(3y), both generally and within specific scientific areas. Both the SJR indicator and the JIF distributions were found to fit well to a logarithmic law. While the two metrics were strongly correlated, there were also major changes in rank. In addition, two general characteristics were observed. On the one hand, journals’ scientific influence or prestige as computed by the SJR indicator tended to be concentrated in fewer journals than the quantity of citation measured by JIF(3y). And on the other, the distance between the top-ranked journals and the rest tended to be greater in the SJR ranking than in that of the JIF(3y), while the separation between the middle and lower ranked journals tended to be smaller. 相似文献
