This article provides an overview of selected Web-based resources containing grey literature in the area of communication disorders. It is geared to practitioners, researchers, students, and consumers seeking reliable, freely available scientific information. Grey (or gray) literature has been defined as "that which is produced on all levels of government, academics, business, and industry in print and electronic formats, but which is not controlled by commercial publishers."1 This paper reviews various general reference sources potentially containing grey literature on communication disorders. This review includes identification of the methods specialists in this field use to obtain this valuable, yet often overlooked, literature. Access points and search tools for identifying grey literature on communication disorders are recommended. Commercial databases containing grey literature are not included. Conclusions presented in this article are considered complementary to traditionally published information resources on communication disorders, such as scholarly journals, online databases, etc.  相似文献

Conclusion In this paper we briefly described the current status of research in the field of digital libraries interoperability, mainly with respect to federated data processing such as permitted within the Open Archive Initiative framework. We then presented the CERN Document Server Software suite that is a free software package main-tained by CERN providing an online digital library solution for mid- to large-sized document repositories. The set of CDSware modules was described and the differ-ences with other existing tools briefly mentioned. Finally we have mentioned a typical usage statistics illustrating the scope of grey literature and networked con-ditions of the CERN Document Server. We pointed out that the current trend in grey literature management goes toward institutional repositories build upon the distributed and federated model. Further research is going on within the CDS collaboration in this area, focused particularly on (i) semantic interoperability using ontologies in distributed and federated data processing and (ii) ranking technologies when searching grey literature in OAI compliant repositories.  相似文献

In the field of scientific, technical, and business information a new legend has arisen. Grey literature (GL), thought by many to have become dormant, has witnessed a rebirth. Grey literature, like the phoenix of ancient legend, has been enkindled by its own resources. New producers and publishers of grey literature have provided us with new forms and types of grey literature. New methods and mediums of storing and distributing grey literature have created new uses for these resources, and in turn, new users of these resources are demonstrating its further capabilities. Government organizations, business and industry, as well as academic institutions have come to view themselves as publishers of grey literature. Their reports, working papers, and policy statements are no longer available only to a limited few in printed form, but are published electronically and are available in networked environments for unlimited retrieval. These new resources, stored in a host of electronic formats, have lured new user groups worldwide, and the exploitation of these resources have not only been made for economic gain, but have greatly contributed to the knowledge base in many fields and disciplines, to the decision making in local and (inter)national government agencies, and in information forecasts for businesses. The rise of this new grey phoenix has emerged over the past quarter of a century from an uncontrolled mass of information to new meta-information applicable for science and industry. phoenix n: A bird of ancient legend said to be the only one of its kind and to live more than 500 years, at the end of which it built for itself a funeral pile, lighted it with the fanning of its wings, and rose again from its ashes; hence, an emblem of immortality; a paragon. this article was adapted from a paper presented at the second U.S. Workshop on Grey Literature (GreyWorks’96) held at College Park, Maryland, USA on November 18, 1996.  相似文献

目前,图书馆对"文献捐赠说明"缺乏应有的重视,并存在着一些问题,体现在文本概念混淆、言辞淡漠,具体内容忽视对非正式出版物的收集,对文献收藏范围界定模糊,提供的受赠方式不够人性化等方面。文章分别选取公共馆和高校馆的"捐赠说明"各一例,进行分析与反思,同时简要对比港台地区部分图书馆使用的"捐赠说明",条缕出可供内地图书馆学习的部分。最后,列出合适的公共馆和高校馆的"捐赠说明"模板。  相似文献

The complex web of information ranges from pure science to applied techniques to management policies. All are important, yet have varying levels of accessibility and authority. Often the apex of the peer-reviewed journal article is considered the most important level discouraging scientists and managers, especially those in developing countries, from populating the other layers of the web that may be considered grey. We are particularly interested in how information produced in developing countries fits into this information web. To do so, we focused on one topic, mangroves, using it as a means to exemplify the complexity of the web of information and reveal publication patterns. Using search tools, we identified 2000–2005 mangrove-related publications regarding Africa and India, analyzed them by author’s location and affiliation, publication format, and availability. Our preliminary analysis suggests that grey literature remains difficult to discover, the peer-reviewed journal is the most popular means of scientific communication, and open archives are just starting to have an impact on scholarly communication. The web of information would be strengthened by improving the discovery of the grey literature through greater visibility and accessibility.  相似文献

This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL).  相似文献

采用光沉积-液相化学法调节电子流向,构建了直接Z型TiO2/Ag/Ag3PO(4 )(TAAPO)光催化材料.通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射仪(XRD)、X射线光电子能谱(XPS)、紫外-可见漫反射光谱仪以及光致发光(PL)光谱仪等手段对其进行表征,并对其在可见光照射下催化降解环丙沙星(CIP)的性能进行了研究.结果表明,当水体pH为3.0,催化剂分散浓度为0.3 g/L,CIP的初始浓度为15 mg/L时,光催化降解体系能够取得最佳的去除效果.在该组条件下,光照120 min CIP的降解率约为99%,并且在经历4个循环后仍然保持了良好的降解效果.在光催化降解CIP的过程中,主要反应活性物种为超氧自由基(·O2  相似文献

Although many governmental and intergovernmental organizations publish vast quantities of grey literature, the importance of the diffusion and impact of this literature are rarely studied. Evidence from an investigation of the grey literature output of GESAMP, the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (sponsored by the UN and several of the UN-family of organizations), indicated that the literature reached scientific readers and was cited. To determine whether that evidence was representative of international intergovernmental bodies, another intergovernmental organization devoted to marine environmental issues, namely, the Gulf of Maine Council on the Marine Environment (GOMC) was studied. GOMC, an American–Canadian partnership, has been working since 1989 to maintain and enhance environmental quality in the Gulf of Maine. Through its own publications and others resulting from studies conducted under contract or in cooperation with other organizations, GOMC provides a complex publishing history for investigation. Over 300 publications were identified and over 500 citations were located after extensive searching using several citation tools. Citation patterns for GOMC publications mirror the findings of the study of GESAMP; grey literature is cited over lengthy periods, but grey literature tends to be cited primarily by other grey literature. Although digital alerting and access tools are increasing in number and coverage, a reliance on grey literature as the primary means of publication continues to pose hurdles for influencing scientific research, public policy, and public opinion. While grey literature is common to organizations such as GOMC and GESAMP, the impact of this literature can be muted because of the limitations of its dissemination and perceptions of its quality.
