The goal of this analysis was to obtain local citation behavior data on undergraduates researching history, political science, and sociology papers. The study found that students cited books and journals even with the availability of web sources; however, usage varied by subject. References to specific websites' domains also varied across subject area. Most of the top journal titles that students referenced were online and locally owned. Students cited a broader range of journal titles than predicted by the Law of Scattering and cited titles across a wide array of subject areas. This data helped identify potential gaps in the library's collection and services.  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

Citation analysis provides valuable information on researchers' information use behavior, and helps librarians make evidence-based collection development decisions. However, no citation analysis of faculty publications in the field of communication has been performed to study communication researchers' information use behavior. This study examined communication faculty publication from 2006 to 2014, analyzing format, age, most frequently cited journals, and their subject areas. Analysis of local holdings provides evidence for the library's role in support of faculty research, and helps librarians articulate the value of libraries.  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

Objectives

This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.

Method

Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.

Results

Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.

Conclusion

Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.  相似文献

This paper contributes to the longitudinal study and representation of the diffusion of scholarly knowledge through bibliometrics. The case of systems biology is used to illustrate a means for considering the structure and different roles of journals in the diffusion of a relatively new field to diverse subject areas. Using a bipartite network analysis of journals and subject categories, a core–intermediary–periphery diffusion structure is detected through comparative analysis of betweenness centrality over time. Systems biology diffuses from a core of foundational, theoretical areas to more specific, applied, practical fields, most of which relate to human health. Next, cluster analysis is applied to subject category co-occurrence networks to longitudinally trace the movement of fields within the core–intermediary–periphery structure. The results of these analyses reveal patterns of systems biology's diffusion across both theoretical and applied fields, and are also used to suggest how the dynamics of a field's interdisciplinary evolution can be realized. The author concludes by presenting a typology for considering how journals may function to support attributes of the core–intermediary–periphery structure and diffusion patterns more broadly.  相似文献

This study analyzes the usage data of a major engineering article database, IEEE Xplore, from 2005 to 2008, at Texas A&M University. Usage data collected from the IEEE Xplore statistics website demonstrated some interesting patterns of user behavior. Usage of the database increased steadily from 2005 to 2007, but dropped in 2008 due to the launch of the library's new website; off‐campus usage was high in the first two years, but plunged in 2007 and 2008. Users from the Department of Electrical and Computer Engineering, and, to a lesser degree, from the Computer Science Department, were identified as major users of the database by IP statistics. The most heavily used journals and articles indicated that solid‐state circuits, microwave, information theory, and power systems were probably among core research areas in electrical and computer engineering for the university. The impact of conference articles in this database increased continuously throughout these years.  相似文献

Statistical analysis and comparison of library print and online holdings are used to reduce shelf area and inform index back-file purchases. Nikki DeMoville of California Polytechnic State University’s Robert E. Kennedy Library combined Counting Online Usage of Networked Electronic Resources (COUNTER) JR2 Access Denied usage reports, holdings information, and print circulation data to identify journals exhibiting a high desirability for online access and low print circulation. In this presentation, DeMoville shared how further combination of this data with ScienceDirect quote lists for back-file journal packages and Web of Science metrics could be used to support the efficient de-selection of print journals, allowing the library to recover the maximum amount of physical space while also acquiring backfile access to those titles most frequently needed in electronic format. The presentation detailed the workflows and comparative methodology used to reach collection management and development decisions for journal coverage, with an emphasis on before and after metrics.  相似文献

Publications of the faculty of the University of Mississippi's School of Business were examined for a citation analysis. The following data were collected: journals cited, which publishers’ journals were cited, age of the citations, and the Library of Congress classification range cited. The results were analyzed by the business school as a whole and by the four major departments in the college: Finance, Management, Management Information Systems/Production Operations Management, and Marketing. The study was undertaken to gain a better understanding of the local faculty researchers’ needs, to examine how the library supports their needs, and to compare the local results with the metaresearch focused on specific subject or journal.  相似文献

Anthropologists at seven universities were surveyed in order to discover: the ways in which they go about locating information of value to them; the information sources that they use and that are of the greatest significance to them; the adequacy of the library service being currently provided to anthropologists; and any opinions they have on the subject of their information needs. Results show that anthropologists; information requirements differ somewhat from those of other social scientists. Reference lists in journals and books are often used to locate information sources; journals are the most important information source. However, cultural anthropologists report that their own field data is their most significant source. Anthropologists use pictorial sources and maps more frequently than social scientists in general do; they also make great use of interlibrary loan. Most of the information needs of the majority of respondents are met by their university's library. Older scholars tend to use databases less than younger ones do; online abstracts and indexes are most important to anthropologists than their print versions are. Some respondents express a great desire for a database which would include current references, abstracts, and articles in anthropology.  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

This study in an academic medical sciences library setting examines the correlation of usage of a matched set of print and online titles, the validity of e-journals usage statistics and the impact of online journals on print journal usage. The print and online usage was determined for 270 journals, both versions of which were available. Print usage was determined annually since 1997 using the reshelving and the error-copies method. Online usage statistics were delivered by five publishers and corrected for redundant multiple accesses. Print journal usage decreased by 22.3 and 30.2% respectively over each of 2 years after the introduction of online journals. Journals published both in print and online lost 30.4% of their print usage within 2 years. The total loss of usage of print-only titles in the same period was somewhat higher, at 45.8%. The average correlation between online and print usage is 0.60 and 0.67 respectively. For the examined titles, users accessed the online versions ten times as often as the print version. Two clearly distinguishable groupings emerged: while with Academic Press and Elsevier, e-journal usage exceeded print usage by a factor of 3 or 4, the e-journals of Blackwell, HighWire and Springer were used on average 14.6 times as frequently as the corresponding print journals. Each usage of a print article cost 2.79-50.82 Euro, each usage of an online article 0.31-15.10 Euro, depending on the publisher. On average, the usage of an online article was 5.4 times cheaper. Within 2-3 years the usage of online journals has outstripped that of print titles by a factor of ten, but the specific spectrum of usage remains much the same as when only print journals alone existed. Print titles not available online suffer a greater decline in usage compared with print/online journals. This confirms that what is read or purchased is determined primarily by ease of access and that there is a steady tendency to reduce the multiplicity of access modes to a manageable few. The availability of journals online seems to have created a new clientele, at least in the case of the German-language Springer journals. The connection between supplier and supply is much less clear with e-journals than it is with print titles. Therefore it is very important to stress and encourage the role of the library as the supplier of this sort of information in the university environment. Collection building issues are discussed in the light of the results.  相似文献

The article reports the results of a survey on the use of printed and electronic journals in a science library. In May 2003, when the survey was conducted, users had already been exposed to electronic journals for a number of years, most of the scientific journals were accessible in electronic format while the print format was still available. The major findings are that more than 80% of the respondents frequently use and prefer an electronic format, irrespective of their rank or age. Most previous studies found an inverse relationship between e-journal usage and age, but these results indicate that by now users of all ages switched to the electronic format not only in terms of usage but of preference as well.  相似文献

The study explores the publication trends of scholarly journal articles in two core Library and Information Science (LIS) journals indexed under ScienceDirect Database during the period for the period 2000–2010, and for the “Top 25 Hottest Papers” for 2006–2010. It examines and presents an analysis of 1000 research papers in the area of LIS published in two journals: The International Information & Library Review (IILR) and Library & Information Science Research (LISR). The study examines the content of the journals, including growth of the literature, authorship patterns, geographical distributions of authors, distribution of papers by journal, citation pattern, ranking pattern, length of articles, and most cited authors. Collaboration was calculated using Subramanyam's formula, and Lotka's law was used to identify authors' productivity. The results indicated that authors' distributions did not follow Lotka's law. The study identified the eight most productive authors with a high of 19 publications in this field. The findings indicate that these publications experienced rapid and exponential growth in literature production. The contributions by scientists from India are examined.  相似文献

It has become unimaginable to provide information – particularly scientific information – without e‐books. They have become part of today's combination of media, which includes printed books and journals, e‐journals, e‐books, and databases. When e‐books first appeared on the market, librarians very quickly formulated their key requirements. The most important requirement is functionality: it must be possible to look through a book chapter by chapter, and also to get a quick overview of a comprehensive monograph. Usage arrangements, including concurrent usage and use for interlibrary loans, are also important. The use of uniform technical standards increases the acceptance of e‐books.  相似文献
