The enormous range of information sources and communication services available on the Internet today recalls the information
explosion and information overload that characterizes this century. We are certainly facing new kinds of information and communication
patterns, based on direct electronic communication between end-users among themselves and/or between end-users and information
sources. Moreover, this new channel of communication provides the opportunity to distribute different types of information,
which in some cases are available only in a networked environment.
The aim of this article is to analyze whether this new scenario has stimulated the production and the direct distribution
of grey literature as well as changing its “traditional” features. The starting point of the study are the Italian WWW servers
of the National Research Council. 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

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

A basic challenge of the Weinberg Report addressed the question of information overload. The Weinberg Panel was extremely
concerned with the proliferation of scientific literature and the specific issue of how to sift through reams of data to find
the “gems” of wisdom, or that which is truly new and useful. In the early 1960s when the report was being written, computers
were not part of the information access and retrieval infrastructure. Writing twenty-five years later, in 1988, Dr. Weinberg
recognized that the panel had not adequately taken into account the impact of the computer and the growth of the information
industry. Today we have a new world of microcomputers and networked information which is fundamentally shifting the paradigm
of scientific communication. We have new capabilities, including electronic publishing, visualization techniques, even virtual
reality. Without getting into a great debate about the definition of “grey literature,” the main characteristics have traditionally
been described as: rapid publication, wariable formats, no public peer review, and no commercial source of general availability.
With networked information and multi-media technology, the new world of grey literature is emerging with an interesting set
of new and revived challenges. This article looks at the most interesting characteristics, and based on them, presents the
thesis that in the 1990s we are facing a new generation of “grey literature”. 相似文献

White papers are a form of grey literature produced by businesses that can be a valuable source of information for librarians and business practitioners. This article reports the results of an exploratory investigation of whether commercial white papers can be successfully located in full-text form through the use of online databases, aggregators, and search engines as an alternative to retrieving the document directly from the Website of the authoring organization. Also examined are the extent of secondary references to these white papers and whether such white papers can be found in library collections. 相似文献

Background: Complementary and alternative medicine (CAM) has succeeded to implement itself in the academic context of universities. In order to get information on CAM, clinicians, researchers and healthcare professionals as well as the lay public are increasingly turning to online portals and databases, which disseminate relevant resources. One specific type of online information retrieval systems, namely the database, is being reviewed in this article. Question: This overview aims at systematically retrieving and describing all databases covering the field of CAM. One of the requirements for inclusion was that the database would also have to be published in a medical journal. Data sources: The databases amed , CAMbase , embase , and medline /Pub Med were searched between December 2008 and December 2009 for publications relevant to CAM databases. The authors’ specialist library was also searched for grey literature to be included. Study selection: All included databases were then visited online and information on the context, structure and volume of the database was extracted. Main results: Forty‐five databases were included in this overview. Databases covered herbal therapies (n = 11), traditional Chinese medicine (n = 9) and some dealt with a vast number of CAM modalities (n = 9), amongst others. The amount of time the databases had been in existence ranged from 4 to 53 years. Countries of origin included the USA (n = 14), UK (n = 7) and Germany (n = 6), amongst others. The main language in 42 of 45 databases was English. Conclusions: Although this overview is quite comprehensive with respect to the field of CAM, certain CAM practices such as chiropractic, massage, reflexology, meditation or yoga may not have been covered adequately. A more detailed assessment of the quality of the included databases might give additional insights into the listed resources. The creation of a personalised meta‐search engine is suggested, towards which this overview could be seen as a first step. 相似文献

The virtual library in action: Collaborative international control of high-energy physics pre-prints
This article discusses how control of the grey literature in high-energy physics preprints developed through a collaborative
effort of librarians and physicists. It high-lights the critical steps in the development process and describes one model
of a rapidly evolving virtual library for high-energy physics information. In conclusion, this article extends this physics
model to other areas of grey literature management. 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.

ABSTRACTThis article examines the role of web archives as a critical source of data for conducting computational communication research. Web archives are large-scale databases containing comprehensive records of websites showing how those websites have evolved over time. Recent communication scholarship using web archives is reviewed, demonstrating the breadth of research conducted in this space. Subsequently, a methodological framework is proposed for using web archives in computational communication research. As a source of data, web archives present a number of methodological challenges, particularly with regards to the accuracy and completeness of web archives. These problems are addressed in order to better inform future work in this area. The closing sections outline a forward-looking trajectory for computational communication research using web archives. 相似文献

Entrepreneurial researchers utilize databases on new and emerging businesses that provide the contact data and other demographic information for research samples. Based on a literature review, the integrity of this data is often assumed, and the vendor's claims as to its accuracy are relied upon. This article tests the accuracy and reliability of one such database, the U.S. New Business database from ReferenceUSA. Specifically, these businesses were contacted to test the validity of the information provided. The research findings suggest that the U.S. New Business database from ReferenceUSA is not a vetted database, and researchers cannot rely on the vendor's promise of accuracy. 相似文献

Summary The objective of this article is to examine some of the valuable philosophical resources available on the Internet, especially for librarians who need to determine what resources to provide to faculty, students, and staff. Some main uses of the Internet for philosophical research are: accessing texts, using search strategies to examine the texts, reading and writing electronic journal articles, accessing information from encyclopedias and dictionaries, browsing through paths of interlinked Web sites, searching the Internet for sources, and participating in online discussion forums. This article examines the Internet as a source of primary and secondary texts, journal literature, research databases, reference works, specialized limited area search engines, organizational information, and discussion lists. The article ends with a philosophical reflection on the transformative effect of information technology on the growth of knowledge. 相似文献
