Publikace: Grey literature: from hidden to visible
Grey literature is information produced on all levels of government, academics, business and industry in electronic and print formats not controlled by commercial publishing i.e. where publishing is not the primary activity of the producing body. (Luxembourg, 1997 - Expanded in New York, 2004, on WWW: http://www.greynet.org/index.html) The role of grey literature in today society was well expressed by Vaska: “It is therefore remarkable how efforts over the past two decades have altered originally preconceived notions of grey literature, resulting in a deeper understanding of how the formation, retrieval, and use of non-traditional material becomes a fundamental companion in one’s research endeavors. The advent and use of new technologies, a prevalent trend in 21st century society, has created increasing awareness of the need to incorporate the grey alongside the white, a boundary that is becoming less distinct and which may become translucent in the not-too-distant future.” (Vaska, 2010) Centralized collecting grey literature started more than thirty years ago. During period 1980 - 2005 non-profit network EAGLE (European Association for Grey Literature Exploitation) created for the acquisition, identification and dissemination of grey literature SIGLE (System for Information on Grey Literature in Europe) database. Nowadays the GreyNet International is a leading organization in dialog, research, and communication between persons and organizations in the field of grey literature. Central access to grey literature is provided by OpenGrey database. OpenGrey is a unique repository providing open access to European grey literature references. OpenGrey is based on the OpenSIGLE/SIGLE database which contains almost 700 thousand records of grey literature. As a multidisciplinary database it covers Science, Technology, Biomedical Science, Economics, Social Science and Humanities. National Repository of Grey Literature will be introduced during the workshop as an example of grey literature on national level.
