ABSTRACT The possibilities of the applications of the structure of bibliographical references in the proceedings of international scientific conferences for the management of information and library service are under discussion. On behalf of such research branches that do not have any specialized periodicals and which researchers are involved in other branches, too, it is demonstrated that the international scientific conference proceedings could be the only reliable source of references that adequately represent such branches and could be used for corresponding bibliometric studies. The results of the studies of disciplinary, chronological and species structures of references cited in the proceedings of the conferences in magnetic fluids and in bone marrow purging and processing are featured and discussed. Some results of detailed citation study of the citedness of particular authors are also presented. It is shown that the practice of taking into account the citation figures referring to only the first co-authors destroys the real picture of impact of individuals (in contrast to what Ferreiro, Ortega & Lara tried to demonstrate in 1977). The basic conclusion: there is a need in the bibliographical index of the proceedings of international scientific conferences of the citation index type. 相似文献

ABSTRACTThis article focuses on the level of international scientific publication by Kazakhstani researchers, and considers the problem of access to international scientific resources in Kazakhstan, a developing country. Key areas of the discussion are Kazakhstan's strategic plans and policies regarding science, roles of international publishers in science, and the relationship between international publishers and the government of Kazakhstan. The article bears the informative meaning and has no research and findings. However, this is a good start point for the author and other Kazakhstani library and information professionals to study the subject more deeply and propose solutions for the good of all. 相似文献

ABSTRACTThe increase in information explosion has left information users with the option of adopting the best means to access and make ethical use of the right information. The role information plays in the society cannot be overemphasized. Information is required for individual, institution and societal development. Hence, efforts must be expended to acquire the right information in a world where information is being produced exponentially with almost no control. Accessing the right information is vital for any form of development hence the academic libraries’ role in ensuring an effective delivery of the right information to their users. Selective Dissemination of Information (SDI) service is one of the means through which libraries achieve this. The study investigates SDI service adoption and use by academics at Redeemer’s University, Nigeria. Statistics kept in the Reference Unit of the library were used to elicit information used for analysis. Sixty-sis (66) out of a total of 135 academics working in the institution at the time the statistics were taken were used for analysis. The study reveals that majority of the academics who sought SDI service were staff of the college of Management Sciences. The study reveals that majority of the academics sought SDI service for the purpose of research. Comments of users from records kept in the unit shows that users’ information needs were adequately satisfied. Users’ comments also reveal areas of improvement on the service. Recommendations geared towards the improvement of SDI service in the university library were given based on the conclusion drawn. 相似文献

This paper reviews a selection of international collaborative efforts in the production of information services and attempts to characterize modes of cooperation. Information systems specifically discussed include: international nuclear information system (INIS); Nuclear Science Abstract (NSA); EURATOM; AGRIS; AGRINDEX; Information Retrieval Limited (IRL); IFIS (International Food Information Service); Chemical Abstracts Service (CAS); MEDLARS; and TITUS. 3 methods of international information transfer are discussed: commercial transactions; negotiated (bilateral) barter arrangements; and contribution to internationally managed systems. Technical, economic, and professional objectives support the rationale for international cooperation. It is argued that economic and political considerations, as much as improved technology or information transfer, will determine the nature of collaboration in the future. 相似文献

ABSTRACT Web-scale discovery services promise fast, easy searching from a single Google-like box, pleasing users and making library resources more discoverable. Some librarians embrace the concept of giving users what they have come to expect from Google, while others are concerned that this will “dumb down” searching and undermine information literacy. In this article we explore the potential impact of Web-scale discovery tools on information literacy, focusing particularly on undergraduate research skills. We review the existing literature and present findings and experiences from two mid-sized academic libraries that have adopted EBSCO Discovery Service as their library home page portal. 相似文献

Summary The reference environment is being transformed by constant changes in computer technologies and communications, as collections and information in general become increasingly accessible electronically. Academic library users now have access to seemingly unlimited information. The explosion of information choices has implications for reference services to all users, particularly adult learners —those students older than the typical undergraduate —who are becoming a large presence on university and college campuses. This paper will explore these implications, stress the need for information literacy, and challenge academic reference librarians to assert themselves in the information arena. 相似文献

ABSTRACTAdding multiple sources of information in the display of Web search results may negatively affect users’ perceptual experience and information-seeking behavior. This claim was established by investigating the impact of different Web search compositions on users’ ability to extract specific information. In this article, we assumed that the quantity and order of different compositions (areas) in the Web search results page may contribute to individual’s ability to find information relevant to their search queries. An eye-tracking device was used to observe and compare the perceptual behavior of 14 users in an information-seeking task. The results showed that the use of different compositions in the display of Web results page significantly influenced users’ perceptual experience by reducing their attention to the organic results area. The quantity of these compositions was found to greatly increase the cognitive load of users when attempting to retrieve information from the organic area, which negatively affects their information-seeking performance. Our finding provides a rationale for further studies to consider the impact of quantity and order of Web page compositions on individuals’ perceptual attention and cognitive load in information-seeking task settings. 相似文献

在大数据环境下,科技文献等各类数据爆炸式增长,却难以提供快捷和有效的科技文献服务,究其原因,主要在于科技文献资源组织没有考虑科技文献用户阅读行为。分析国内外用户阅读行为,不仅要对科技文献用户阅读行为进行分析,更重要的是对科技文献阅读用户行为知识进行组织和分析,才能为科技文献服务提供支撑。文章以提高科技文献知识服务的效率为目标,以科技文献用户阅读行为为研究对象,从知识组织角度分析科技文献用户阅读行为知识,借助大数据分析方法,对用户阅读行为知识组织的准备、获取、关联分析以及服务等组织过程,总体架构科技文献阅读行为知识组织模型,并把用户阅读行为分析融入到科技文献的知识组织和服务过程中,将用户阅读行为信息升华为用户知识需求,最终指导知识提供部门为用户提供有效的科技文献知识服务。 相似文献

Summary With the rapid advances in information technology, the proliferation of information resources and formats, and the increasing complexities of access and evaluation, libraries recognize the necessity for a dynamic information literacy program that will address the needs of all categories of users. University faculty constitute one group of users to which the systemic college library increasingly endeavors to extend and market its services and programs, including its information literacy training workshops. A consideration of this library/classroom faculty relationship in the context of the adult education literature, as well as successful models that have been employed in this effort, provide insight on ways in which the library can successfully accomplish its information literacy training objectives among this group. 相似文献
