Grey literature is defined as that which is not formally or commercially published. It is therefore difficult to trace through bibliographic databases. Examples include company reports and other internal documents. A good starting point is to search the internet, such as Google or Google Scholar but there are alternative that might make the search easier and quicker.
OpenSIGLe is an open access resource that allows you to search for grey literature produced in European Community countries. The database covers a wide range of subjects. All of the content is in English.
GreyNet aims to provide a platform for discussion and research on grey literature by undertaking a number of activities including:
- organising an international conference
- distribute information on grey literature electronically
- create web based resources
- facilitate discussion using distribution and discussion lists
- produce a journal
