Grey Literature

Grey literature is information that is produced and disseminated outside of traditional peer-reviewed publishing. Examples of grey literature include reports, theses, dissertations, official documents, informal communication, research-in-progress, or clinical trials produced by government agencies, academic institutions, or business. Grey literature can be difficult to find, but invaluable to your research.
