Definition of Grey Literature
According to Monash University, “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.”
What is Grey Literature in Research
Grey literature refers to information and knowledge resources produced and disseminated outside traditional publishing and distribution channels, such as government reports, conference proceedings, theses, dissertations, working papers, and technical reports. These types of literature are typically not commercially published, widely distributed, and often not peer-reviewed.
Grey literature can be a valuable source of information for researchers, policymakers, and practitioners, as it often contains up-to-date and specialised information that is not available in mainstream publications.
However, accessing and assessing the quality of grey literature can also be difficult due to its diverse formats and sources, and the quality of grey literature always remains a cause of concern for the researchers.
What are the Different Types of Grey Literature?

- Government reports: These can include official reports produced by government agencies, departments, or committees.
- Conference proceedings: These cover the papers, posters, and presentations given at academic or industry conferences.
- Theses and dissertations: These are research papers that students write for their graduate degree programs.
- Technical reports: These are reports that researchers or experts produce in a particular field to document their research findings or other technical information.
- Working papers: These include preliminary research papers produced by researchers and are often shared with other researchers for feedback or discussion.
- Newsletters: These cover publications produced by organisations, associations, or government agencies to provide regular updates on a particular topic.
- White papers: These are authoritative reports or guides that provide information and recommendations on a particular topic.

- Up-to-date and timely information: Grey literature is often produced quickly and provides up-to-date and timely information on current research topics, policies, and practices.
- Diverse perspectives: Grey literature can come from a wide range of sources, including government agencies, non-profit or organisations and industry associations. This can provide diverse perspectives on a particular research topic.
- Complement to traditional research sources: Grey literature can provide a complementary source of information to traditional research sources such as journal articles and books, helping to fill in any gaps in the literature.
- Cost-effective: Many grey literature sources are freely available online, making them a cost-effective source of information for researchers.
Overall, incorporating grey literature into research can enhance the scope, depth, and reliability of research findings and provide a more complete picture of a particular research topic.
