Grey literature refers to information and research outputs that are not formally published in traditional academic or commercial publishing channels. This type of literature can include a wide range of materials, such as:
- Reports: Technical reports, research reports, and policy briefs from government agencies, NGOs, and think tanks.
- Theses and Dissertations: Graduate and doctoral research that may not be published in journals.
- Conference Proceedings: Papers and presentations that are shared at conferences but not formally published in journals.
- Working Papers: Early-stage research findings that are shared for feedback before formal publication.
- White Papers: Authoritative reports that often advocate for a specific position or solution to a problem.
- Preprints: Draft versions of research articles shared publicly before peer review.
- Newsletters and Bulletins: Periodicals published by organizations that share updates and insights.
Grey literature is valuable for research because it can provide timely information, emerging trends, and unique data not found in peer-reviewed sources. However, it can vary in quality and rigor, so critical evaluation is essential when using it for research or decision-making.
