A Note on Searching Grey Literature Sources
Many resources are listed several times throughout this guide. Producers of grey literature often create multiple typesof literature (e.g. reports, research findings, and meeting materials) so you may find several useful resources on one website.
Always use the advanced search option when searching for grey literature. Doing so can save you valuable time by narrowing your search appropriately.
