Using data from Ulrich’s Periodicals Directory, and the extent of coverage by abstract information resources and indices, the worldwide output of periodicals and proceedings (including those represented in electronic form) is studied. A quantitative characterization of the entire output of worldwide editions, as well as its abstracted portion is given. To provide complete reception of needed subject information and cover a maximum number of periodicals using an information system, a method for selecting several databases, which makes it possible to get a maximum coverage of primary sources with a certain amount of duplication, is proposed. Data on abstracting are obtained as the result of analyzing the input stream of approximately 700 databases and indices. Basic statistics for the abstracted stream are given for a number of companies: VINITI (All-Russia Institute for Scientific and Technical Information, Russian Academy of Sciences), CSA (Chemical Abstracts Service), Thomson Corporation, Elsevier, CABI Publishing, CAS (Cambridge Scientific Abstracts), and several others. A list of 25 of the largest abstract journals and referral databases, with respect to the number of periodicals represented in them, is given. 相似文献

Currently important Russian and foreign sources of scientific and technical information related to robotics are discussed. An attempt is made to analyze scientific and technical periodicals of the relevant subject matter, selected from the global knowledgebase of periodicals, that is, Ulrich’s Directory of Periodicals. Leading scientific serials attributed to robotics that have the best bibliometric indicators according to the global information and analytical systems Scopus and Web of Science are identified. The specific features of the classification of the subject matter in various classification systems and rubricators for scientific and technical information are considered. Special attention is given to Russian scientific periodicals on robotics included in Russian scientific electronic library (eLibrary.ru) and information resources of All-Russian Institute for Scientific and Technical Information of Russian Academy of Sciences (VINITI RAS). Particular focus is placed on the problem of access to these and other kinds of information sources on robotics, which is of great importance for researchers and specialists working in this field. 相似文献

This paper analyzes the content of large (40000–80000 doc./year) and average (20000–30 000 doc./year) databases on physico-mathematical
and some technical sciences for 1996–2010 that are in the databank of the VINITI RAS. This research on arrays with large coverage
of periodicals (from 2500 to 9000 sources in different thematic fragments) permits one to draw the conclusion that the record
in the form 1 : x : x
3, where x is the Bradford parameter, is suitable for the Bradford rule as the ratio of the number of sources in three zones
with a similar documental content. The subsequent specification of this ratio requires the standardization of all sources
by their average monthly content and maximum supplementation of the zones of nuclear and profile journals with omitted articles. 相似文献

The results of an analysis of the international flow of periodical and proceedings publications in different priority areas (the nanosystem industry and materials, information-telecommunication systems, rational wildlife management, and power and power conservation) and of critical technologies entering into them are presented. As the main sources of the information on foreign and Russian databases (SCOPUS, Current Contents. CSA, Ulrich’s Periodicals Directory, RZH VINITI, and the Russian Academy of Sciences) open scientific Internet resources were used. For correctness, a separate preparation of the terminological base of each subject area was made. Lists of publications on the detailed publishing and data about the availability of access to them on various Internet platforms were compiled as a result. The characteristics of the most important electronic resources for each area are given. The publishing houses and companies responsible for the major publications on the considered subjects not accessible at present to the Russian scientific community through widely known consortia (NEIKON and the Russian Federal Property Fund) are revealed. 相似文献

Solar cells of the third generation (after the bulk and thin-film ones that are mainly based on inorganic semiconductors, mostly of silicon) use the leading technologies of the 21st century, including nanotechnologies based on nanomaterials, mainly based on nano-structured or ultrafine inorganic semiconductors, graphene, fullerenes, as well as polymers and low-molecular-weight organic semiconductors. This paper compares the results of an analysis of publications on solar cells, mainly nanostructured and nanoscale cells, that are reflected in the RZh Fizika VINITI RAN and included in the Web of Science database. 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

Background: Complementary and alternative medicine (CAM) has succeeded to implement itself in the academic context of universities. In order to get information on CAM, clinicians, researchers and healthcare professionals as well as the lay public are increasingly turning to online portals and databases, which disseminate relevant resources. One specific type of online information retrieval systems, namely the database, is being reviewed in this article. Question: This overview aims at systematically retrieving and describing all databases covering the field of CAM. One of the requirements for inclusion was that the database would also have to be published in a medical journal. Data sources: The databases amed , CAMbase , embase , and medline /Pub Med were searched between December 2008 and December 2009 for publications relevant to CAM databases. The authors’ specialist library was also searched for grey literature to be included. Study selection: All included databases were then visited online and information on the context, structure and volume of the database was extracted. Main results: Forty‐five databases were included in this overview. Databases covered herbal therapies (n = 11), traditional Chinese medicine (n = 9) and some dealt with a vast number of CAM modalities (n = 9), amongst others. The amount of time the databases had been in existence ranged from 4 to 53 years. Countries of origin included the USA (n = 14), UK (n = 7) and Germany (n = 6), amongst others. The main language in 42 of 45 databases was English. Conclusions: Although this overview is quite comprehensive with respect to the field of CAM, certain CAM practices such as chiropractic, massage, reflexology, meditation or yoga may not have been covered adequately. A more detailed assessment of the quality of the included databases might give additional insights into the listed resources. The creation of a personalised meta‐search engine is suggested, towards which this overview could be seen as a first step. 相似文献

The need to continuously evaluate resource usage, whether in print or online, has been a challenge for libraries for a long time. The shift in resources to digital formats has made gauging the utility of resources more convenient as well as enabling cross database comparisons on various parameters. In this context, the article explores the aggregator databases subscribed by Indian Institute of Management Ahmedabad library. The study compares EBSCO's Business Source Complete, EBSCO's Academic Search Premier, Proquest's ABI INFORM Complete, JSTOR, and Project Muse packages in terms of the features available, usage, and the most used journals in these packages. 相似文献

Entrepreneurial researchers utilize databases on new and emerging businesses that provide the contact data and other demographic information for research samples. Based on a literature review, the integrity of this data is often assumed, and the vendor's claims as to its accuracy are relied upon. This article tests the accuracy and reliability of one such database, the U.S. New Business database from ReferenceUSA. Specifically, these businesses were contacted to test the validity of the information provided. The research findings suggest that the U.S. New Business database from ReferenceUSA is not a vetted database, and researchers cannot rely on the vendor's promise of accuracy. 相似文献
