Deciding whether to search grey literature depends on your discipline, questions, and your research type.
- Scoping Reviews should include grey literature, unless there is a reason to omit it. If there is a reason to omit grey literature, note it in your protocol materials.
- Examples of how your research question and subject area may require grey lit:
- Social Sciences
- Does your question relate to public education or school age children? Many times relevant information is published in District, State or Federal level reports, not just peer reviewed journals.
- Does your research question relate to policy? You may need to look at information from think tanks.
