Grey Literature

What it is, its value, where to search for it, and how to evaluate it.

What are they?

Organizations and associations involved in research, advocacy, policy, and professional practice—such as non-governmental organizations (NGOs), international organizations, think tanks, research institutes, industry associations, and policy centres—are major producers of grey literature. Unlike academic institutions, these entities often publish practical, applied, or policy-focused research. These outputs are often not published in traditional scholarly journals and may be disseminated only as a by-product of the organization's work and on their website, making them key sources of grey literature.

Why include them in your search?

  • Organizations often publish reports more quickly than peer-reviewed journals, especially on emerging issues or urgent topics.
  • Work is often aimed at practitioners, decision-makers, or the public, offering practical insights into real-world application, current debates, or political contexts.
  • Sources may represent unique perspectives from community-led organizations and viewpoints that differ from academic or government sources.
  • Often generate original data through surveys, fieldwork, or stakeholder consultations that may not be published elsewhere.
  • In under-researched areas or marginalized communities, grey literature from organizations may be the most comprehensive or only available information.
