There are enormous quantities of information available to researchers on the Internet, of varying levels of quality. Now, more than ever, it is important that academic publishers make best use of their journals and provide their readers with access to this high‐value content, in a form that can be easily found and used. To that end, Taylor & Francis have taken up the challenge of satisfying researchers' need to have all relevant content available at their fingertips, by digitizing their older journal content, creating subject‐based collections of backfiles and putting them online. This article provides an insight into the ‘why’ and ‘how’ of the process of digitization of Taylor & Francis's journal archives. The fact that these online backfiles are being requested, purchased, and used demonstrates the added value that publishers may hold in their archives. 相似文献

The Martland Hospital Library converted many of its periodical backfiles to 16 mm microfilm cartridges. Some details of program implementation, user reactions, costs, and problems are discussed. In a teaching hospital library microfilm in cartridge format has been well accepted by patrons, in part because the need to read from a projection screen has been minimized by granting liberal printing privileges. 相似文献

With the advent of e-journal preservation projects and publisher digitization of journal backfiles, academic libraries have begun to move their corresponding print volumes of these titles to storage to avoid duplication and save space. This article examines the supporting justifications, outreach mechanisms, and logistical procedures undertaken at American University Library to relocate the entire bound journal collection to offsite storage in order to address severe physical space constraints and to support patron use of and preference for electronic journal content. In addition, the article presents preliminary data regarding the use of bound volumes sent to storage and an overall analysis of this transformational project. 相似文献

Scans of journal articles originally published in print, otherwise known as digital journal backfiles, benefit library patrons by providing near instantaneous access to important older information and full-text searchability. Digital backfiles can serve as a reliable surrogate for their corresponding print journals which could be removed from the library, freeing up space for other patron services. Both benefits are realized when the scanned articles are of sufficient clarity to replace the print versions. Several studies have analyzed small and subject-narrow sections of Elsevier's digital backfile. This article contains a scan-quality analysis from 1578 journals that contain nearly four million articles and represents a significant portion of Elsevier's entire digital journal backfile. We divided journals into three categories and five discipline-specific classifications and compared them by logistic regression for differences in scan quality. Approximately 4.2 % of the articles analyzed contained illegible text, tables, or figures. This data may inform a library's acquisition, retention and space-planning decisions that in turn will affect a patron's access to and use of electronic journal articles. 相似文献

The Combined Retrospective Index to Journals in Sociology, 1895-1974, is a six volume author and keyword-in-category index to the backfiles of 123 sociological journals which affords unprecedented coverage in one file. In tests of its completeness of coverage, however, omissions in author and keyword files of articles were detected. Further difficulties of retrieval arose in a keyword search for articles in a sample bibliography on "status inconsistency." Whatever the causes these deficiencies in comprehensiveness and in indexing result in low rates of recall, and caution is urged concerning decisions to purchase or use the set. 相似文献

This study's purpose was to establish the image quality of photographs and figures in online journals verses the print format of five Elsevier titles. The images were evaluated on a point scale, taking three issues out of each journal every five years from 1970 to 2000. The study discovered that there is a significant loss of content in the online photographs from 1970 to 1995. The data found in this study provide important discussion points when considering the purchase of electronic journal backfiles. 相似文献

The long-standing cooperative culture within the research library community should serve as a useful foundation for building regional cooperative agreements to support repositories of print journal backfiles. Serious storage constraints facing Iowa State University, the University of Iowa, and the University of Wisconsin-Madison mandated an effort to tackle this problem in a deliberative and coordinated way. An inter-institutional Task Force was formed to design and implement a process with a selected group of titles as a pilot project. The immediate goal was to liberate shelf space with an eye toward the future development of a consortial collection management plan for the storage of print journals among the three institutions. 相似文献

Despite its rising position as a first-class research object, scientific software remains a marginal object in studies of scholarly communication. This study aims to fill the gap by examining the co-mention network of R packages across all Public Library of Science (PLoS) journals. To that end, we developed a software entity extraction method and identified 14,310 instances of R packages across the 13,684 PLoS journal papers mentioning or citing R. A paper-level co-mention network of these packages was visualized and analyzed using three major centrality measures: degree centrality, betweenness centrality, and PageRank. We analyzed the distributive patterns of R packages in all PLoS papers, identified the top packages mentioned in these papers, and examined the clustering structure of the network. Specifically, we found that the discipline and function of the packages can partly explain the largest clusters. The present study offers the first large-scale analysis of R packages’ extensive use in scientific research. As such, it lays the foundation for future explorations of various roles played by software packages in the scientific enterprise. 相似文献

Libraries have joined consortia to increase their purchasing power, and in recent years they have been focusing on electronic journal packages. Purchasing a publisher's entire journal list, often called a Big Deal, seemed to be a good answer at first, but many librarians and libraries found that this solution was restrictive on their budgets and detrimental to their collections. In response, publishers became more flexible about allowing libraries to collaborate on the journal title lists. Survey results show that these collaborations are becoming more prevalent because the benefits outweigh the difficulties. 相似文献

Librarians and faculty members are now working together through Open Access (OA) publishing to make faculty-produced scholarly content available to researchers worldwide. The University of South Florida Tampa Library has been working with the Berkeley Electronic Press (bepress) Digital Commons platform to create a substantial institutional repository (IR) that includes OA journals, conference proceedings, and data sets, among other materials. Library staff members are currently involved in a variety of activities, including negotiating memoranda of understanding, loading backfiles, registering Digital Object Identifiers (DOIs) with CrossRef, designing layout, doing final publication steps, and assisting with technical issues. In 2011, the IR, Scholar Commons @ USF, went live, allowing the library to pull fragmented collections previously hosted on other platforms into a single system with improved discoverability. This article discusses how the repository was established, what is involved, lessons learned, and plans for future directions. 相似文献

Microcomputers and database management packages reduce the difficulties of collecting and analyzing ILL requests. This article examines earlier ILL/collection development studies to identify important ILL record elements for collection analysis. Further, this article reports on the results of a telephone survey of available ILL database management packages to determine whether the elements considered important in the earlier manual studies are being included in these new software packages. The article concludes that through the use of ILL database management packages, ILL activity analysis can be easily incorporated into ILL workflow and quickly passed along to subject selectors. 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

Computational text analysis has become an exciting research field with many applications in communication research. It can be a difficult method to apply, however, because it requires knowledge of various techniques, and the software required to perform most of these techniques is not readily available in common statistical software packages. In this teacher’s corner, we address these barriers by providing an overview of general steps and operations in a computational text analysis project, and demonstrate how each step can be performed using the R statistical software. As a popular open-source platform, R has an extensive user community that develops and maintains a wide range of text analysis packages. We show that these packages make it easy to perform advanced text analytics. 相似文献

外文电子期刊数据库捆绑纸本订购模式分析 总被引：1，自引：0，他引：1
随着期刊市场纸本与电子共同出版模式的形成,以及期刊出版业的垄断集团化,为了获取高额利润,一些出版商采取纸本与电子版捆绑销售模式来销售电子期刊数据库,其捆绑模式有保留现有纸本订购、规定一个最低订购额以及提供E-only和纸本+电子捆绑三种形式。随着图书馆馆藏数字化,出版商的纸本捆绑销售出现了一些转变,有的出版商允许用户将纸本刊转成电子刊,有的允许用户取消纸本载体转而支付电子内容费,有的取消纸本捆绑启用E-only模式,但这些转变并没有给用户节省多少费用,并没有在真正意义上取消纸本捆绑,只是出版商换了一种销售方式而已。 相似文献

ABSTRACTThe ease and effectiveness of patron-driven (demand-driven) acquisitions has helped to optimize many academic libraries’ acquisitions budgets. Libraries are increasingly turning to e-books as an alternative to purchasing multiple copies. Academic libraries have for years been forced to purchase large packages of e-books that are of questionable financial value because so much of the content is not used. The number of content units downloaded from large e-book packages by university patrons is not growing. At the same time, the number of checkouts of print books is declining. Advantages of e-books over print are discussed. Also mentioned are a few drawbacks, particularly the fact that European Union countries impose a higher level of value-added tax (VAT) on them than on print books. The author presents a case study analyzing the first two years of experience with the Ebook Library (EBL) platform at the Tallinn University of Technology Library, giving an overview of the advantages and successful measures of demand-driven acquisition in the form of short-term loans. 相似文献

Introduction: In 2003/4 the Information Management Research Institute, Northumbria University, conducted a research project to identify the barriers to e‐learning for health professionals and students. The project also established possible ways to overcome these barriers. The North of England Workforce Development Confederation funded the project. Methodology: The project comprised a systematic review of the literature on barriers to and solutions/critical success factors for e‐learning in the health field. Fifty‐seven references were suitable for analysis. This review was supplemented by a questionnaire survey of learners and an interview study of learning providers to ensure that data identified from the literature were grounded in reality. Results: The main barriers are: requirement for change; costs; poorly designed packages; inadequate technology; lack of skills; need for a component of face‐to‐face teaching; time intensive nature of e‐learning; computer anxiety. A range of solutions can solve these barriers. The main solutions are: standardization; strategies; funding; integration of e‐learning into the curriculum; blended teaching; user friendly packages; access to technology; skills training; support; employers paying e‐learning costs; dedicated work time for e‐learning. Conclusions: The authors argue that librarians can play an important role in e‐learning: providing support and support materials; teaching information skills; managing and providing access to online information resources; producing their own e‐learning packages; assisting in the development of other packages. 相似文献

The library's mission is to support the information and educational needs of its users. E-journal “Big Deals” offer libraries one method of maximizing the resources available to their users, but, with libraries now experiencing flat or decreasing budgets, these Big Deals present budgetary difficulties for libraries. They also remove collection development decisions from the control of the libraries themselves. Some libraries have canceled their Big Deals, resulting in problems. This article presents the results of an online survey of libraries regarding these bundled journal packages. 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

Some mathematical CAD packages are inadequate in computing the composite functions involving the product of an exponential function and an error function complement. These functions arise in physical applications, such as problems in diffusion. Their importance warrants a composite treatment. If their component factors are computed individually, discontinuities in the evaluations arises, as shown in some CAD packages. An improved algorithm is presented which overcomes this deficiency, and provides a fast evaluation. Such evaluation is successful even using floating point numbers with single precision. The potential for numerical overflow associated with large arguments has been overcome. 相似文献
