ABSTRACT Digital collections of full-text e-books are proliferating on the Web and provide a wealth of open content for students. To examine whether academic libraries are providing a digital gateway to these resources, ten e-book titles from open digital collections were searched in the online catalogs and Web pages of ten academic libraries serving distance learners. Only three of the digital collection e-books were available from any of the library catalogs, and none were found on library Web pages. Availability of the ten e-book titles through Google and other digital discovery tools also had mixed results. Continued projects for improved delivery of open online content are necessary. In order to fulfill their role as digital gateways for their academic communities, libraries must pursue metadata standards to support cross-searching, collaborative projects, and development of e-resource search software, which integrates with the library catalog. 相似文献

SUMMARY York University of Pennsylvania, like many libraries, has been grappling with the issue of serials control for titles in aggregator databases. Historically the librarians have adapted the methods they used (word processing lists, lists on Web sites, online catalog, etc.) to provide journal access as technology has advanced. However, as the number of titles has increased beyond the capabilities of the staff, other options needed to be reviewed. In 2001 a task force was set up to evaluate three management systems: Serials Solutions, JournalWebCite, and TDNet. The librarians reviewed the technical requirements, the display and organization, searching capabilities, how often the systems are updated, usage statistics, management reports, cost and other special features. 相似文献

In this paper we map the scientific journals from Ibero‐American countries indexed in the Web of Science and Scopus. Data were collected from the journals' websites. Of 879 journals in the two databases, Spain accounted for 35.6% of the titles, Brazil 28.5%, and the remaining 11 countries together 35.9%. Medicine had the most titles in almost all countries, with 28.9% of the total, followed by agricultural and biological sciences (particularly in Brazil) with 14.9%, and social sciences with 11.5%. A digital format was used by 95% of the journals and 82% were open access, with an even higher level of open access in Latin America. The publishers were mainly universities (37.7%) and associations (31.1%). Ibero‐American countries, with the exception of Spain, do not have a long tradition as scientific journal publishers, but in the last few years they have gained in importance as players in scientific communication with the use of new business models for journals. 相似文献

ABSTRACT Librarians at the Arnold Bernhard Library of Quinnipiac University were concerned with the usage levels of their electronic reference titles. They added the titles to the library's Web page, made individual records in the online catalog, and even established links between an OPAC keyword search and a search through electronic reference titles. It was still felt that the collection was underutilized. In 2007, the Automation Librarian began a project to add one more level of access to these titles—a graphic interface that simulated the process of walking into a reference room and picking out a title. A preliminary version was loaded in the Fall of 2007, and early results indicate that it has found an audience. 相似文献

The aim of this study is to investigate the link between the use of electronic resources and the academic output of researchers in the state universities of Castile and Leon (Spain) in the period 2006 to 2011. An analysis was undertaken of the consumption of contents distributed to the Universities of Burgos, Leon, Salamanca and Valladolid by three multidisciplinary suppliers whose materials are widely used: ScienceDirect, SpringerLink and Wiley. In investigating academic output, the databases Web of Science (WoS) from Thomson Reuters and Scopus from Elsevier were taken into account. The consumption of electronic academic contents at the four universities shows an upward trend over the years considered. There is an undoubted preference for titles distributed by ScienceDirect, striking in all the institutions. The study confirms that academics from the areas of science and technology were the most frequent users. The field of Chemistry registered the highest rates of both consumption and academic production, followed at some distance by publications related to Food Science and Technology, in respect of preferred title use, and by Physics with regard to communication of research results. Many of the journals selected for publications belonged to the suppliers investigated. Nevertheless, the work showed no absolute direct correlation between titles selected for academic publication and titles used from the platforms analyzed. 相似文献

The authors interview librarians and out-of-print book dealers to find out how out-of-print academic titles are being handled. Librarians discuss successful strategies and various ways of identifying and pursuing out-of-print titles needed in their collections. Vendors and book dealers address the special needs of libraries, plus their methods of finding OP books. Recommended OP search strategies include advertising, using reference works, using vendors and dealers, and searching both Internet and Web databases. The report concludes with a listing of dealers that were mentioned favorably by academic librarians. 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

This article examines approaches to creating museum Web sites that offer quality experiences to online users. In six case studies, museum Web developers in the U.S. and Canada describe how they have made the most of available human and financial resources. The development history of each site offers insights into the origins of a design and its subsequent versions, and describes the influence of institutional missions, philosophies, success indicators—and financial and human resources, the most crucial factors. The study found considerable variety in the backgrounds, expertise, titles and training of people developing Web sites within institutions. Web teams developed “exchange” experiences through online discussion, and by creating links among users, or between museum staff and users. In three case studies, Web sites encouraged visitors to cycle between online and on‐site museum visits. Web developers describe using quantitative and qualitative online audience research strategies. WebTrendsTM software has enabled Web teams to report complex log analyses. Creating online experiences in partnership with users is the intention of Web developers. 相似文献

The Web of Science is no longer the only database which offers citation indexing of the social sciences. Scopus, CSA Illumina and Google Scholar are new entrants in this market. The holdings and citation records of these four databases were assessed against two sets of data one drawn from the 2001 Research Assessment Exercise and the other from the International bibliography of the Social Sciences. Initially, CSA Illumina's coverage at journal title level appeared to be the most comprehensive. But when recall and average citation count was tested at article level and rankings extrapolated by submission frequency to individual journal titles, Scopus was ranked first. When issues of functionality, the quality of record processing and depth of coverage are taken into account, Scopus and Web of Science have a significant advantage over the other two databases. From this analysis, Scopus offers the best coverage from amongst these databases and could be used as an alternative to the Web of Science as a tool to evaluate the research impact in the social sciences. 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

Kenneth Frazier's call for avoiding the “Big Deal,” an aggregation of journals that publishers offer as a one-price, one-size-fits-all package, has won some converts. Concerns exist over the inclusion of titles in aggregated packages that are neither wanted nor used by library patrons and the financial impact those titles are having on library budgets. Most libraries, particularly smaller and medium-sized institutions, perceive great benefit from the aggregated packages. OhioLINK has succeeded in negotiating license agreements that allow for annual reductions by selecting titles in the packages for discontinuation. The Big Deal is continuing to evolve, even as it begins to fade away. 相似文献

Analysis of observed use of general, humanities, social science and general science periodicals revealed an adherence in the upper 90% of total use to Bradford's Law of Dispersion. General and social science titles were used to a far greater extent than humanities titles. In their order of significance, indexing, bibliographic instruction, and housing decisions increased the use of any given title. Applied as opposed to theoretical disciplines experienced a higher overall use percent of their titles. Foreign language titles experienced minimal use regardless of their subject content. 相似文献

Planning that title: Practices and preferences for titles with colons in academic articles 总被引：4，自引：0，他引：4
Colons play a hidden but important role in the planning and writing of effective titles for academic articles. This paper presents three studies of current practices in using colons and four studies of students' and academics' preferences for titles with and without colons. The practice studies showed disciplinary differences in the use of colons (with a greater use in the arts than in the sciences). They also showed that more single authors than multiple authors use colons. Using colons in the titles of academic articles had no effect upon their subsequent citation rates. The preference studies showed that students and academics generally preferred titles with colons to titles without them. However, these results depended to some extent on the materials and the methods used. 相似文献
