ABSTRACT Budget constraints in academic libraries have led them to seek alternative means of providing patrons with articles without subscribing to every journal requested. In order to determine how academic libraries were doing this for business articles, a study was conducted of selected academic libraries at universities offering MBA degrees. The results of the study indicate that academic libraries use a combination of ways to obtain business articles that are not held in their collections. In addition to traditional interlibrary loan, libraries are providing access to full text databases, subscribing to electronic journals and using commercial document delivery services. This article examines the influence that technology and, especially the Internet, has had on the ability to offer patrons quicker, and often better, access than ever before. In spite of tight budgets, academic libraries are finding innovative ways to fund these services in order to provide timely service to their business faculty and students. 相似文献

The ever-growing number of full-text electronic databases and their increasing availability has helped to create greater expectations among the undergraduate students who use them in their research. A study was made of nearly three hundred students enrolled in composition classes to determine the indexes and databases most commonly used for assignments and whether having the full text of journal articles online played a role in shaping the nature of their research. The survey results confirmed the authors' belief from encounters at the reference desk that students are becoming dependent on the availability of full-text databases and are using them in some cases to the exclusion of all other information sources. 相似文献

ABSTRACT East View Information Services is now providing online access to nine serial publications from the Russian National Bibliography, beginning with 1998 issues. Though East View has been successful with large full-text databases for newspaper and journal articles, images, and statistical tables for several years, this was our first project dealing specifically with bibliographic data. Building a platform for bibliographic records has been more difficult than previous projects. The article discusses why the project was so challenging, how various problems were solved, advantages of the online format, and plans for future improvements. 相似文献

ABSTRACT Based on his experience, the author summarizes what reference/collection development librarians and library users want and expect from aggregator databases, and what's needed from database vendors and from librarians to meet these expectations. Particularly important are content quality, reliability, modularity, and affordability, interface simplicity and flexibility, and reliable congruence between and integration of print and electronic editions. From vendors, librarians should demand more and better content guarantees, purchase options, communication of content details and changes, full-text searching, and persistent URLs for individual titles. Librarians should provide analyzed cataloging and holdings for all titles in aggregator databases, keep these records current, fully integrate them with records for print and other electronic editions, and incorporate them into web catalogs, in addition to providing other web access tools such as browsable title lists. 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

Journal articles are often made available prior to assignment to an issue, using labels like “early view,” “advanced online publication,” “ahead of print,” “online first,” or “in press.” While making articles available before an issue can speed up the scholarly communications cycle, a negative effect can be observed when full text is delivered through aggregator databases like EBSCO, ProQuest, or Gale products. This study assessed issue assignment delays across 18 journals which have full text aggregated in EBSCO's CINAHL Ultimate. Results show that articles published first in an early-view state are only available in the aggregator after they have been assigned to an issue. Any database-specific full-text delays (“embargos”) are then calculated from issue date rather than online publication date, leading subscribers who access the journals via aggregators to experience extended delays ranging from months to years in length. 相似文献

SUMMARY In this study, a group of recent law articles was examined to determine the proportion of cited resources that are easily findable online. Searches were conducted in databases such as LEXIS and Westlaw, and on the Internet, for full-text versions of every source cited in seven articles. The results have been broken down into 13 categories, including “federal cases,” “books,” “foreign law,” and “legal periodicals pre-1990.” Not surprisingly, coverage differs widely between the categories. Overall, the study found that 77% of the 1,984 citations in the articles reviewed are available online. The article concludes with a general discussion of why the percentage is likely to increase in the future. 相似文献

ABSTRACTAcademic libraries provide intellectual access (discovery and procurement) to the full text of electronic journal articles through traditional library technologies like discovery layers, link resolver software and knowledge bases. These technologies mainly rely on accurate title-level metadata to successfully deliver journal articles to library users. Open Access articles pose a difficulty for many participants in the e-journal supply chain, including libraries and publishers, as Open Access status is a property of the article, not the title. A review of the literature examines: the impact of Open Access on intellectual access through traditional library technologies, current proposed solutions, and emerging technologies. 相似文献

Abstract Popular for their ability to provide full-text linking, OpenURL link servers, such as SFX, can also interface with online catalogs and interlibrary loan modules, giving library users the ability to locate articles in print or request items not owned by their local institution. This article examines four different approaches to integrating print holding information into SFX, detailing the advantages and drawbacks of each approach. The ultimate goal is to provide end-users with comprehensive, dynamic access to the full range of core library services, including online full-text, print materials, and interlibrary loan. 相似文献

Objectives:
The purposes of this study were: to determine the number of articles requested by library users that could be retrieved from the library''s collection using the library catalog and link resolver, in other words, the availability rate; and to identify the nature and frequency of problems encountered in this process, so that the problems could be addressed and access to full-text articles could be improved.Methods:
A sample of 414 requested articles was identified via link resolver log files. Library staff attempted to retrieve these articles using the library catalog and link resolver and documented access problems.Results:
Staff were able to retrieve electronic full text for 310 articles using the catalog. An additional 21 articles were available in print, for an overall availability rate of nearly 80%. Only 68% (280) of articles could be retrieved electronically via the link resolver. The biggest barriers to access in both instances were lack of holdings and incomplete coverage. The most common problem encountered when retrieving articles via the link resolver was incomplete or inaccurate metadata.Conclusion:
An availability study is a useful tool for measuring the quality of electronic access provided by a library and identifying and quantifying barriers to access.Highlights
- Lack of holdings, including access to recent articles restricted by embargoes, was the most common barrier to locating full text, accounting for over 90% of all identified problems.
- Availability rates for electronic articles varied by year of publication and by the database in which the OpenURL request originated.
- Link resolver error rates varied widely based on the source of the request and frequently resulted from incomplete or inaccurate metadata.
Implications
- An availability study is an inexpensive, practical tool for assessing the quality of electronic access to journal articles.
- The results of an availability study can help libraries identify barriers to access and thereby allocate limited resources to areas that will provide the most benefit to users.
- Link resolvers might be more accurate if the quality of metadata in OpenURLs was improved and the behavior of full-text targets was standardized.
- Collection and acquisition problems: The library may not subscribe to the desired journal, or the article and/or journal may be unavailable for some other reason.
- Cataloging and holdings problems: The journal may be cataloged or indexed incorrectly, or the library''s holdings data may be wrong.
- Technical problems: Problems may occur with the journal provider''s site or the library''s proxy server.
- gather actual user requests (or simulate them)
- try to fill those requests using the same tools and methods a user would use
- record what happens
- analyze the results

This study investigates the methods by which faculty obtain scholarly articles, books, and chapters. It focuses on full-text retrieval rather than discovery, drawing on a survey of 529 full-time faculty at U.S. colleges and universities in the Carnegie master's—large and master's—medium categories. When seeking articles, faculty rely mainly on their home-institution library collections, freely accessible online resources, and interlibrary loan. The situation is different for books, however; faculty most often purchase the books they need. Despite the continuing importance of formal access mechanisms (home-institution library collections and interlibrary loan), faculty rely on other sources of full text—informal access mechanisms—for 50% of the articles and 66% of the books they use. Nearly 25% get more articles from the open web than from any other source, and substantial minorities report heavy reliance on other sources. In particular, faculty sometimes use other libraries, often relying on current or past affiliations (e.g., part-time teaching) or on the user accounts of family, friends, and colleagues. Many are critical of their university library collections, but most are satisfied with freely accessible online resources and interlibrary loan. 相似文献

Abstract Since early 1995, the University of Nevada, Reno (UNR) libraries have offered its user community a new and enhanced service through the InfoTrac SearchBank from Information Access Company (1AC). Available through the libraries' online catalog, this service offers useful features like remote access through the Internet, indexing and abstracting, fall-text access to 460 journal titles, as well as a powerful search engine. The service also provides access to a family of databases in areas such as, general reference, health, business and law information. The purpose of this article is to familiarize the business librarians and researchers with the business databases (General BusinessFile ASAP and Businesslndex Backfile) available through the InfoTrac SearchBank service. 相似文献

SUMMARY There is a proliferation of Internet sites covering environmental themes. Many of these sites provide reference information in varying degrees. This article highlights environmental Web sites that provide a wide range of pertinent reference sources to a diverse audience. More than 50 highly selective Web sites are included in this paper. Some of these Web sites provide access to library catalogs, full-text articles, and other online resources. The Web sites in this article are in five categories: portals, government sites, special issues, general sites, and databases. 相似文献

ABSTRACTWeb page views of databases by title and databases by subject pages, in conjunction with COUNTER Database Report 1 and Journal Report 1 statistics, were examined to determine what impact a migration to Primo, a Web-scale discovery layer, had at Central Washington University Brooks Library. The analysis determined that the first year post-migration (2015) compared to the two years pre-migration (2013–14) saw a decline in Web page views of database Web pages, journal full-text article requests, and database record views and result clicks. The implementation of Primo thus had a noticeable negative impact on both direct database access and overall electronic resource usage during the first year post-migration. 相似文献

Result merging methods in distributed information retrieval with overlapping databases 总被引：5，自引：0，他引：5
In distributed information retrieval systems, document overlaps occur frequently among different component databases. This
paper presents an experimental investigation and evaluation of a group of result merging methods including the shadow document
method and the multi-evidence method in the environment of overlapping databases. We assume, with the exception of resultant
document lists (either with rankings or scores), no extra information about retrieval servers and text databases is available,
which is the usual case for many applications on the Internet and the Web.
The experimental results show that the shadow document method and the multi-evidence method are the two best methods when
overlap is high, while Round-robin is the best for low overlap. The experiments also show that [0,1] linear normalization
is a better option than linear regression normalization for result merging in a heterogeneous environment.
