ABSTRACT

This overview of the core concept applied to journals defines the relevant terminology and cites specific examples of core lists. Ten approaches for determining core journals (subjective judgment, use, indexing coverage, overlapping library holdings, citation data, citation network/co-citation analysis, production of articles, Bradford's Law, faculty publication data, and multiple criteria methods) are reviewed and the practical applications of core journals lists are explained. Theoretical and practical problems associated with the core concept and core journal lists are discussed and a taxonomy for classifying core journal lists is outlined.  相似文献

PurposeThis paper aims to examine whether Altmetric data can be used as an indicator for identifying predatory journals.Design/methodology/approachThis is an applied study which uses citation and Altmetrics methods. The study selected 21 predatory journals from the Beall's list and Kscien's list, as well as 18 non-predatory open access journals from the DOAJ's list, in the field of Library and Information Science. The Altmetric score for articles published in these journals was obtained from the Altmetric Explorer, a service provided by Altmetric.com. Web of Science was used to search for citation data of articles published in these journals.FindingsThe predatory journals almost have no presence in social media, with poor Altmetric score. In contrast, non-predatory open access journals have a high presence rate and Altmetric score. There is a significant positive correlation between the number of articles cited and the number of articles having Altmetric score among non-predatory open-access journals, but not among predatory journals. Poor Altmetric score may be viewed as a potential characteristic of predatory journals, but other indicators would also need to be considered to determine whether a journal is predatory.Originality/valueDistinct from the traditional research methods, this study combined citation analysis and Altmetrics analysis. By comparing the characteristics of predatory journals and non-predatory open access journals, the findings contribute to the identification of predatory journals.  相似文献

The journal impact factor (JIF) has been questioned considerably during its development in the past half-century because of its inconsistency with scholarly reputation evaluations of scientific journals. This paper proposes a publication delay adjusted impact factor (PDAIF) which takes publication delay into consideration to reduce the negative effect on the quality of the impact factor determination. Based on citation data collected from Journal Citation Reports and publication delay data extracted from the journals’ official websites, the PDAIFs for journals from business-related disciplines are calculated. The results show that PDAIF values are, on average, more than 50% higher than JIF results. Furthermore, journal ranking based on PDAIF shows very high consistency with reputation-based journal rankings. Moreover, based on a case study of journals published by ELSEVIER and INFORMS, we find that PDAIF will bring a greater impact factor increase for journals with longer publication delay because of reducing that negative influence. Finally, insightful and practical suggestions to shorten the publication delay are provided.  相似文献

Abstract

This paper describes a grant-funded research project to relocate selected print journal runs, for which an electronic version is available, to remote storage from the shelves of campus libraries at the University of California. During the project, users will rely on the electronic version of selected journals. Data, including costs associated with the project, usage of print journals, usage of electronic journals, as well as user behavior and attitudes, will be gathered and used to develop long-range strategies and institutional policies.  相似文献

Objective:This study aims to identify the core journals cited in the health care management literature and to determine their coverage in the foremost bibliographic databases used by the discipline.Methods:Using the methodology outlined by the Medical Library Association''s Nursing and Allied Health Resource Section (NAHRS) protocol for “Mapping the Literature of Nursing and Allied Health Professions,” this study updates an earlier study published in 2007. Cited references from articles published in a three-year range (2016–2018) were collected from five health care management journals. Using Bradford''s Law of Scattering, cited journal titles were tabulated and ranked according to the number of times cited. Eleven databases were used to determine coverage of the most highly cited journal titles for all source journals, as well as for a subset of practitioner-oriented journals.Results:The most highly cited sources were journals, followed by government documents, Internet resources, books, and miscellaneous resources. The databases with the most complete coverage of Zone 1 and 2 were Scopus, Web of Science Core Collection, and PubMed, while the worst performing databases were Health Business Elite, ABI/Inform, and Business Source Complete.Conclusions:The literature of health care management has expanded rapidly in the last decade, with cumulative citations increasing by 76.6% and the number of cited journal titles increasing by nearly 70% since the original study. Coverage of the core journals in popular databases remains high, although specialized health care management and business databases did not perform as well as general or biomedical databases.  相似文献

ABSTRACT

Researchers must choose between many sources when obtaining journal articles. University of Toledo faculty and graduate students in the sciences, pharmacy, and engineering were surveyed to ascertain their preferences in journal article formats and features, and their awareness, frequency of use, and preference ranking of four services: traditional interlibrary loan, electronic journals, and faxes from either a storage depository or the UnCover document delivery service. Speed and print quality topped the desired features; faxing was the least desirable format. Electronic journals and interlibrary loan were the most used services, though there are indications that interlibrary loan is used reluctantly.  相似文献

Abstract

Publishers and librarians do not agree on the use of electronic journal files as a source for interlibrary loans. The efficiency possible in electronic ILL is valued by the supplying libraries and of concern to publishers. Publishers do not accept CONTU photocopying guidelines as applicable to electronic ILL. This position is based on the historical context in which CONTU occurred and the specific wording of the CONTU report. No agreement on new guidelines has been possible to date, resulting in the need for individual license negotiations. Copyright-cleared document delivery is one alternative. Alternate models for broad database access to electronic journals is another. A new attempt to define guidelines for resource sharing is a third possibility.  相似文献

Abstract

Using the BUBL Journals service as a rich source of data, this article outlines different methods of measuring usage of electronic journals, suggests that different types of access may be mapped to the user activities of browsing, reading and searching, and draws some inferences about why different titles have differing patterns of usage. It also proposes that by measuring the ‘search-to-browse’ ratio of a journal it is possible to assess whether journals are being used primarily for research and reference purposes or mainly for current awareness and casual browsing.  相似文献

Abstract

The continual escalation in academic journal prices threatens the quality and future of academic library collections. This situation arises from market forces that react to, and take advantage of, the unique characteristics of academic libraries and scholarly publishing. These characteristics include the unique role of academic libraries, in their mission of serving as accessible repositories of knowledge, and the unique activity of scholarly publishing, in which every journal title is unique without a close substitute. The combination of these of factors leads to the lowest price elasticity of demand for the libraries and the highest degree of product differentiation for each journal title. While some solutions being offered to alter the dilemma hold promise, the unique characteristics of the market appear to discourage more equitable pricing without a radical restructuring of the industry or of the relationships between the consumers and the producers of academic journals.  相似文献

This paper presents data regarding the publication of Chinese English‐language journals (CELAJs), building on previously published information to investigate the status, growth, and international penetration of these journals. The article also presents three case studies of CELJs to demonstrate different strategies for achieving internationalization. We find that there has been rapid growth in CELJs between 2006 and 2011 but mostly in the science, technology and medicine disciplines. There are now 435 CELJs, of which 62.3% are published in association with a western publisher. Partnership has been shown to provide immediate benefits to an established successful journal (Cell Research), has helped to relaunch an established title in English (Bamboo and Silk), and has enabled the successful launch of a new journal (Global Health Research and Policy). The authors conclude that there are three criteria for successful international CELJs: increased visibility, good editorial boards, and international publishing partnerships.  相似文献

Aim:The purpose of this study is to identify and describe the citing behavior of geomatics postgraduate students at the Wuhan University in China. These students constitute one of the main user groups of Wuhan University Library and the analysis of their use of literature (through the means of citation analysis) can yield valuable insights against which to benchmark and inform collection development policy and other services at the Information Technology Library (ITL) at Wuhan University.Design/methodology/approach:In this project, 9317 citations in 21 PhD and 180 MSc theses submitted at the Wuhan University in the years of 1988, 1996, and 2004 were analyzed. All cited materials were divided by output format (monographs, proceedings, journal articles) and the more in-depth analysis was conducted for all cited journals. The following characteristics of the cited journal literature were analyzed: subject, age, language, and dispersion of journal titles.Findings:An increased use of journal literature in bibliographies of geomatics theses was observed over time. A trend to increase citations to international conference proceedings was also noted as well as a trend to cite more journals in disciplines other than surveying and mapping. It was also noted that, over time, citations to documents in languages other than Chinese and English have significantly decreased (in some cases, disappeared). Large dispersion among the most frequently cited journals in different time periods (only 25% of titles were repeated in 1988, 1996, and 2004 top ranking journal lists) was also noted. It was also noted that the core of geomatics literature is expanding (it now takes 42% of journal titles to cover 80% of all citations).Practical implications:By analyzing citation patterns of the graduate students of geomatics in China, we can track the developments and changes within that discipline in China and can compare these trends internationally (e.g. increased role of a journal, the importance of conference proceedings, domination of the English-language sources, dispersion of journal literature, and increasing multidisciplinarity of the discipline). The techniques and methods used in this study can be replicated to study other disciplines. Also, it is hoped that the findings of this research will inform collection development planning, development of reference services, and information literacy training.  相似文献

This study established a technological impact factor (TIF) derived from journal impact factor (JIF), which is proposed to evaluate journals from the aspect of practical innovation. This impact factor mainly examines the influence of journal articles on patents by calculating the number of patents cited to a journal divided by the number of articles published in that particular journal. The values of TIF for five-year (TIF5) and ten-year (TIF10) periods at the journal level and aggregated TIF values (TIFAGG_5 and TIFAGG_10) at the category level were provided and compared to the JIF. The results reveal that journals with higher TIF values showed varied performances in the JCR, while the top ten journals on JIF5 showed consistent good performance in TIFs. Journals in three selected categories – Electrical & Electronic Engineering, Research & Experimental Medicine, and Organic Chemistry – showed that TIF5 and TIF10 values are not strongly correlated with JIF5. Thus, TIFs can provide a new indicator for evaluating journals from the aspect of practical innovation.  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

This paper introduces the Hirsch spectrum (h-spectrum) for analyzing the academic reputation of a scientific journal. h-Spectrum is a novel tool based on the Hirsch (h) index. It is easy to construct: considering a specific journal in a specific interval of time, h-spectrum is defined as the distribution representing the h-indexes associated to the authors of the journal articles. This tool allows defining a reference profile of the typical author of a journal, compare different journals within the same scientific field, and provide a rough indication of prestige/reputation of a journal in the scientific community. h-Spectrum can be associated to every journal. Ten specific journals in the Quality Engineering/Quality Management field are analyzed so as to preliminarily investigate the h-spectrum characteristics.  相似文献

Abstract

One of the persistent problems in finding journal literature is that there are so many places to locate such information. UNCG's Jackson Library has simplified the process with Journal Finder, a locally developed software solution that seamlessly integrates electronic journal content, pay-per-view content, local print holdings, unmediated document delivery (fully funded by the Library), and interlibrary loan, for comprehensive, unmediated, “one stop shop” access to journal articles. Also integrated into this solution are remote authentication options, title-level access to journals wherever possible, and the development of cross-linking between vendored database products for both title-level and even article-level access.  相似文献
