Online public access catalogs (OPACS) enable the user to search a library's holdings in ways never before possible and to know the status of the desired items before going to the shelf. Serials constitute an important part of a library's collection. Holdings information is a necessary adjunct to bibliographic information. The online catalog of the future will give access to serial literature beyond that held by a library. As users become accustomed to the OPAC's capabilities their expectations for access to information will rise. Libraries should be aware of the factors to be considered when incorporating serials information into an online catalog. They must make decisions on what information their users need and what form of access and display will best meet that need. 相似文献

Because the neurosciences affect many areas of society and culture, they receive much public attention. Brain research and other focuses of neuroscience are regularly featured in the mass media, calling on neuroscientists to serve as sources. Based on 30 semi-structured interviews with neuroscientists in the United States and Germany, this article analyzes neuroscientists' motivations to interact with journalists, their perception of problems with the media reporting of neuroscience and media contacts, and the strategies they apply in order to gain some control over the coverage. Results show that most neuroscientists perceive benefits of media coverage and are willing to cooperate with journalists and conform to their expectations, but only to a certain degree. Neuroscientists perceive problems regarding the quality of coverage, risks related to public visibility and negative consequences of being distracted from research and scientific publication because of the time demands of media interactions. The scientists discussed several strategies to improve this perceived cost–benefit ratio. 相似文献

Abstract With the transformation of the card catalog into the online public access catalog came the expectation of its increased functionality. For the most part, today's online catalogs perform an expanded list of tasks quite effectively. Bibliographic utilities, system vendors, and individual libraries continue to improve bibliographic retrieval by providing new and better services through the catalog. In spite of these improvements, many observers believe that online catalogs have reached their maturity. Today's information environment includes a wealth of material to which online catalogs cannot provide universal and up-to-date access. Increasingly, librarians are turning to federated searching portal applications to find a means of managing the flood of digital information that threatens to engulf users. This chapter describes essential functionality of such tools, suggesting directions and strategies for improving them. The author concludes that, while the online catalog will continue to function as the principal tool for access control of the library's physical collections, the federated searching portal will ultimately serve as the library's principal Web gateway to digital resources. 相似文献

The aim of the study is to measure the effects of information resources and services of a regional information resources centre (NR CRI Library, Umudike), on the work of agricultural scientists within South Eastern Nigeria. The adequacy and relevance of resources and services were also examined.One hundred and forty-one copies of a structured, self-administered questionnaire were sent to 140 scientists and one Head Librarian. Ninety-nine (70%) were retrieved and analysed. Data were also generated from intervies and a randomly selected sample, from documentary sources and observations. Analysis focused on library use, resources, services, effects of use on performance, relevance and adequacy of resources and services. Simple analytical tools such as graphs, charts and tables were used to elucidate library use, operations, benefits, effects of use on performance, relevance and adequacy of resources and services.Results showed that research objective (20%) was the most common reason why scientists sought information and that information “effectively improved” the work of 73% of scientists. It also showed that among six other technical determinants that are essential for agricultural research, the importance attributed to the contribution of information to the success of research varied between groups of scientists. This trend was also observed in the amount of work achieved by scientists with the use information. The highest (20·4%) showed respondents who accepted that 31–40% of their research work was achieved with the use of information. The 相似文献

我国信息资源配置的模式分析(一) 总被引：30，自引：8，他引：22
信息资源配置是信息资源共享的必要前提,是国家信息战略的重要内客。信息资源配置的模式因信息资源的存在形式不同而异,文献信息资源配置多以宏观调控模式为主,网络信息资源配置则多以市场驱动模式为主。但无论哪一种模式,其配置基础都是信息用户及其信息需求的分布和聚合状况,都存在一定的配置风险。 相似文献

Scholarly research content contains vast stores of valuable, untapped knowledge and records the practical experiences of millions of research scientists. Analysis of this data to create useful actionable information promises to yield not only significant benefits for individual researchers, but also to provide a valuable market intelligence tool for companies that view scientists as their main customers. This article outlines some of the work that we are doing to unlock the intrinsic value of research content for the benefit of readers and advertisers. We report some findings of our internal market research, which illustrates the importance of documentary evidence and collegial recommendations to scientists when it comes to evaluating materials for scientific research. Furthermore, we outline some of the steps that we are taking to deliver this valuable, structured information to scientists and customers, in a fashion that is commercially viable and mutually beneficial for our company and the publishers with which we work. 相似文献

ABSTRACT Academic libraries customize, support, and provide access to myriad information systems, each with complex graphical user interfaces. The number of possible information entry points on an academic library Web site is both daunting to the end-user and consistently challenging to library Web site designers. Faced with the challenges inherent in designing online search interfaces and the ever-growing amount of resources available online, Virginia Commonwealth University Libraries sought to explore how to build effective search interfaces that, at the same time, support a wide variety of computer users and provide comprehensive access to assorted collections of electronic resources. Over a nine-month period, the libraries designed, implemented, and tracked the usage of two different search interfaces on their home page. Each interface allowed users to choose between four different search targets. In this case study, the authors discuss the complexities of designing search interfaces, outline findings from the nine-month study, evaluate the effectiveness of the two interface designs, and talk about future research in these areas. 相似文献

Background: Reviews of how doctors and nurses search for online information are relatively rare, particularly where research examines how they decide whether to use Internet‐based resources. Original research into their online searching behaviour is also rare, particularly in real world clinical settings. as is original research into their online searching behaviour. This review collates some of the existing evidence, from 1995 to 2009. Objectives: To establish whether there are any significant differences in the ways and reasons why doctors and nurses seek out online information; to establish how nurses and doctors locate information online; to establish whether any conclusions can be drawn from the existing evidence that might assist health and medical libraries in supporting users. Methods: An initial scoping literature search was carried out on PubMed and CINAHL to identify existing reviews of the subject area and relevant original research between 1995 and 2009. Following refinement, further searches were carried out on Embase (Ovid), LISA and LISTA. Following the initial scoping search, two journals were identified as particularly relevant for further table of contents searching. Articles were exclused where the main focus was on patients searching for information or where the focus was the evaluation of online‐based educational software or tutorials. Articles were included if they were review or meta‐analysis articles, where they reported original research, and where the primary focus of the online search was for participants’ ongoing Continuing Professional Development (CPD). The relevant articles are outlined, with details of numbers of participants, response rates, and the user groups. Results: There appear to be no significant differences between the reasons why doctors and nurses seek online Internet‐based evidence, or the ways in which they locate that evidence. Reasons for searching for information online are broadly the same: primarily patient care and CPD (Continuing Professional Development). The perceived barriers to accessing online information are the same in both groups. There is a lack of awareness of the library as a potential online information enabler. Conclusions: Libraries need to examine their policy and practice to ensure that they facilitate access to online evidence‐based information, particularly where users are geographically remote or based in the community rather than in a hospital setting. Librarians also need to take into account the fact that medical professionals on duty may not be able to take advantage of the academic model of online information research. Further research is recommended into the difference between the idealised academic model of searching and real world practicalities; and how other user groups search, for example patients. 相似文献

Chinese academic libraries have been devoting great effort into introducing next-generation online public access catalogs (OPACs) in order to provide a better user experience. However, there is a lack of empirical research on their usage. In this study, a transaction log file from a typical next-generation OPAC, the Wuhan University Library OPAC, formed the basis for an investigation of users' information behavior, using a clickstream data analysis framework. The 26,732,368 clickstream records in the original log file were cleaned, parsed, coded, then analyzed at the footprint, movement, and pathway levels. The results showed that the users relied heavily on the single-box simple search interface, seldom involved themselves in an exploratory search process, and preferred page navigation over search refinement when interacting with search results. The OPAC was used as a lookup tool to locate known academic resources and as a personal information management tool to utilize basic library services, instead of as a discovery tool as intended. 相似文献

The increasing availability of computerized information sources and networking capabilities, along with the proliferation of microcomputers in faculty homes and offices, has led to increased demands for direct access to databases. The librarian's role as online search intermediary appears to be changing from performing searches directly to aiding users in doing their own searching. The Research Libraries Information Network (RLIN), one of the major cataloging utilities, offers a wealth of bibliographic information in both its online union catalog, and its many specialized files. The University at Albany Libraries participated in a pilot project involving faculty end-user access to RLIN. This paper reports on the Libraries' experience with the pilot project and the continuing end-user access program for faculty. Despite some reservations about the relative user-friendliness of the RLIN search system, the author enthusiastcally endorses the use of RLIN as an end-user database. 相似文献

Traditional approaches to the concepts of "authorship" and "responsibility" of scientific and technical documents are examined in printed versions of selected abstracting services. The importance attributed to the work of the individual or the parent organization differs between discipline-oriented services developed for the most part by scientific and technical societies, and services announcing reports of government sponsored research developed by the U.S. Federal Government. These differences are linked to the contexts in which scientific and technical research are performed. Differences in approach which are apparent in printed sources may be obscured when databases are mounted for online searching and search vendors impose their own processing requirements on the bibliographic data. 相似文献

The nature of bibliographic instruction in this hospital library continues to evolve. As the library makes easy-to-master, menu-driven tools for online searching available to end users, the demand for this service and the accompanying training increases. The demand for formal sessions covering research techniques is also increasing. Upon request, the library offered an extended research orientation to the housestaff in Obstetrics and Gynecology in May of 1993. An introduction to the use of CD-ROM was included to highlight its usefulness for citation verification, author searches, and for periodic current awareness searches on a particular topic. The UMH Library staff strive to offer the most current and comprehensive facilities and services to their users. These include automated access to the library's book, journal, and audiovisual holdings using the Data Trek system; online bibliographic searching by library staff and end users using CD Plus MEDLINE on CD-ROM and Grateful MED software; participation in clinical rounds to provide research support for clinical care; and several types of bibliographic instruction. In addition to the informal teaching of library research techniques that the library staff offers on a daily basis, the Library at Union Memorial Hospital is pleased to be able to provide a formalized and evolving bibliographic instruction program. 相似文献
