Introduction: Locating reports of trials from journals not indexed in the major databases presents difficulties to systematic reviewers, and may be a factor in improving the reliability of the reviews. Objectives: To identify and make available reports of controlled trials from the Australasian Medical Index (AMI). To measure the quality of indexing of trials in AMI. Methods: Using a highly sensitive search strategy consisting of methodology indexing and free‐text terms, records from AMI were read for reports of controlled trials. Trials meeting the criteria were submitted for inclusion in The Cochrane Controlled Trials Register (CCTR) and assessed for the quality of their indexing. Results: 3621 records were downloaded, of which 512 were identified as reports of controlled trials (317 RCTs; 195 CCTs) and submitted to CCTR. The precision of methodology indexing terms was 60%, but sensitivity just 18%. The quality of indexing of trials was generally poor with only 50 tagged with the RCT/CCT publication type term. 453 reports (88%) were not previously available in CCTR. Conclusions: The large proportion of trials found to be unique to the AMI database increases the pool of studies available to systematic reviewers, and helps ensure CCTR remains the most comprehensive source of trials. 相似文献

Use of dynamic links from subject-based finding aids to records for electronic resources in the OPAC is suggested as one method for by-passing the OPAC search interface, thus making the library's electronic resources more accessible. This method simplifies maintenance of links to electronic resources and aids instruction by providing a single, consistent access point to them. Results of a usage study from before and after this project was completed show a consistent, often dramatic increase in use of the library's electronic resources. 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

Abstract Librarians and patrons can access many thousands of electronic journals today. Librarians who incorporate records for these journals into their OPACs will maximize the journals' access and use, but accurately tracking them can be difficult. This paper describes a commercial solution to the problem. Serials Solutions combines aggregator title lists with CONSER MARC records to improve access to these titles. This paper reviews the benefits and challenges associated with this process, and identifies several areas in which aggregators and OPAC vendors can improve the services they provide, to facilitate this process. 相似文献

This paper describes use of the Ohio College Library Center (OCLC) on-line union calolog and its check-in subsystem in a pilot project centering on the United States documents collection in a large university library. The project extended from the fall of 1974 through July 1976. In August 1976 it became apparent that the process and its product were no longer "experimental" or a "project" but had become part of the library's normal operation, accepted by staff and by users. Activities covered are destined to evolve with expanding capabilities of OCLC, and will certainly be dependent upon the new MARC format, Monthly Catalog. Nevertheless, at this time, a large, viable collection of depository and nondepository items, many timely, are processed and on the shelf, available immediately through the public service terminals by entry and title, and are used by patrons with no access to card files relating to these materials. 相似文献

This article discusses the emergence of academic publishing in a fast‐growing transition economy, Vietnam, where the race has heated up to publish in international journals, preferably with a high impact factor, and to accelerate the indexing of domestic journals. Within the fields of SSH alone, the publication output grew by 17% a year in the 2008–2018 period, encouraged by government policies and financial incentives for researchers. This review demonstrates an environment where there is sufficient financial growth to support increased R&D but limited skills and knowledge of how to increase quality publication output, either within national or international journals. The article highlights the drivers of increasing scientific publication output, as well as the traps and pitfalls that follow this competition. It suggests that there are opportunities for publishers and other organizations to improve ethical and practical publishing issues and to develop co‐publishing agreements that will increase the visibility of the country in international academia. The article indicates the harsh reality of pursuing higher publishing standards in academia, a world that has long been dominated by authors and publishers from industrialized countries. 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11.

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

During the last twelve years there has been a phenomenal increase in the number of periodicals focusing on women's studies and feminism. Initially these titles were ignored by most indexing and abstracting services. The earliest indexing, by the Alternative Press Index and Women Studies Abstracts appeared in 1971 and 1972. Since 1975 there has been a marked increase in the indexing of these periodicals; and the Wilson indexes have added half a dozen new titles so far in the 1980s. The interdisciplinary nature of women's studies requires that researchers and librarians be aware of the indexes which can best satisfy their needs. 相似文献

The Management & Economics Library at Purdue University began a major physical and conceptual renovation four years ago. The conceptual renovation involves a rethinking of library faculty and staff roles and responsibilities based on the library's and university's strategic directives. The LearnLab space is being used as a springboard to create new partnerships, to implement our new roles, and to transform the perspective of an academic library's present capability. This article will highlight the variety of opportunities that have arisen by leveraging the LearnLab space. 相似文献

Basic library orientation at the University of Haifa tries to address the usual problems inherent in orientation programs plus those arising from the nature of Israeli academic institutions—a need to teach access and use of materials in at least two languages, a diverse student population, and a difficult OPAC. In the past both tours and lectures were tried. In 1994, a workbook used at the OPAC terminals by pairs of students met with success. In 1996, the reference department decided to improve on this method by tailoring the material taught to new students' needs and by adding a PowerPoint presentation to give information about the library's organization, collections, and services. The new strategies were most successful. 相似文献

The following paper examines current United Nations (UN) serial publishing practices. Using the series listed in the "Current Serials' list in the 1985 cumulated UNDOC: Current Index as the sample population, this study discusses UN serials in terns of their: (a) physical and intellectual formats, @) place of publication, c) frequency of publication, (d) survivability, indexing, and availability. The study concludes that UN serials follow a definite pattern of publication, despite apparent variability found in the UNDOC "Current Serials" list. The need for better bibliographic control for UN serials is also discussed. 相似文献
