Primary sources are sometimes found in 'grey literature'. What is 'grey literature"? It is information produced outside of traditional publishing and distribution channels and can include reports, policy literature, working papers, newsletters, government documents, speeches, white papers, urban plans, and so on.
Because grey literature (usually) does not go through a peer review process, the quality can vary a great deal. Be sure to critically evaluate your source. One advantage of grey literature is that it is usually more current as it takes months and years to get peer-reviewed articles published. Another advantage is that marginalized communities can more freely and easily publish works.
For an extensive list of the types of documents that might be considered grey literature, see Document types in grey literature (from GreyNet International).
Identify organizations that might be publishing this type of information on topics that you're interested in and then to search their websites—paying close attention to website sections with names like "Documents", "Reports", and "Library". Consider government agencies, non-profits, professional associations, research institutes, and other organizations, based on the research you have already done.
There is some grey literature in Google Scholar such as conference papers, theses, reports, and dissertations. You can use our theses and dissertations database, too.
