What is ‘grey literature’?<br />"document types produced on all levels of government, academics, business and industry in print and electronic formats that are protected by intellectual property rights, of sufficient quality to be collected and preserved by library holdings or institutional repositories, but not controlled by commercial publishers i.e., where publishing is not the primary activity of the producing body.” <br />[12th International Conference on Grey Literature, Praugue]<br />
Why search for it?<br />Includes information that cannot be obtained elsewhere. <br />Detailed research results are often contained in doctoral thesis, conference papers, and preliminary project reports. <br />Circulated before being made available through formal publication <br />Most up to date information available.<br />
Characteristics of grey literature<br />Not primarily used for commercial publishing<br />Not part of traditional publishing channels<br />Few bibliographic controls - ISBN, ISSN. <br />May be high quality - but not peer reviewed<br />Difficult to find. Not historically included in indexes or abstracting databases<br />Ephemeral or transient in nature<br />Protected by intellectual property rights - Copyright legislation still applies.<br />
Use a search engine<br />Google Scholar Searches across institutional repositories and open access information. Good for 'grey literature' but note that many academic publishers are not included. Access from: http://scholar.google.com/<br />Scirus Comprehensive scientific research tool. Search for journal content, scientists' homepages, courseware, pre-print server material, patents and institutional repository and website information. Access from: - http://www.scirus.com/<br />Exalead The advanced search offers some different options to Google. Access from: http://www.exalead.com/search/<br />Microsoft Academic Search Strong for Computer Science. Access from: http://academic.research.microsoft.com/<br />Intute This is an academic subject directory, often useful for finding research collections, e-prints and special collections. Use this if you are unfamiliar with a subject area and need a starting place. Note that it is no longer being updated. Access from: http://www.intute.ac.uk<br />
Tips<br />Limit format<br />Limit domain<br />Look for a Google Custom Search Engine<br />
Search for information<br />Search engine's can't access information contained within databases. Consider your topic. Include terms in your search to help find collections of material about your subject<br />
Who published it?<br />Search for membership bodies, trade associations, professional associations, research organisations. <br />Look for Universities with a particular research strengths in your subject area. Check for an institutional repository that holds academics conference papers, pre-prints, project reports.<br />Consider searching Europa (website of the European Union) for details of pan-european projects and background information, supporting legislation. Look for the appropriate Directorate General, or use the guide to Publications and Documentation.<br />
Searching within sites<br />Check institutions websites for publications catalogues, research repositories and databases, libraries, archive, or digital library<br />
Institutional repositories<br />An institutional repository is an online database used to collect electronic copies materials created by it's own organisation. University's have been the main adopters of this tool. It might include original research articles, thesis, dissertations, project reports, technical reports and pre-prints (Initial drafts of research articles, before they have gone through the peer review process). Contents may depend on publisher's copyright, and the institutions policies. Most are 'self-archiving' and depend on the researcher to deposit a copy. To find an institutional repository, use the search tools, or search the website of an institution directly.<br />

Conference Proceedings<br />Search Web of Knowledge to find Conference Proceedings. You will need an Athens username and password in order to be able to search.<br />Web of Knowledge is a scientific database that includes book reviews, original research articles, reviews and conference papers. To limit the search to find only conference papers, run the search as normal. Use the 'refine' functions to limit your search to conference materials. Click on 'more options' under 'Document Types' chose 'Conference Proceedings' and click 'refine' to see the new list of results. In 'Refine Results' menu, scroll down to 'Conference Titles' to see the list of conference titles and quickly select the relevant conferences, or eliminate unwanted conferences.<br />
