You may need to take a different approach when searching for grey literature compared to searching for formal research studies through databases. This is because the search interfaces where you find grey literature can be very basic and won't have the same advanced search functionalities.
Database that collects citations from various types of documents, including policy papers, parliamentary transcripts, government guidelines, and research from think-tanks.

The largest abstract and citation database of international peer-reviewed literature: journals, books and conference proceedings. It also has smart tools to track, analyse and visualise research.
Multidisciplinary resource which enables simultaneous cross-searching of a range of citation indexes and databases. It provides access to research tools like cited reference searching and the Journal Citation Reports.
Preprint servers are online archives, or repositories, containing works or data associated with various scholarly papers that are not yet peer reviewed or accepted by traditional academic journals.
These resources provide research from policy experts, think tanks, inter-governmental and non-governmental organisations.
A think tank is a body of experts that performs research and provides advice and ideas in specific areas. They cover topics relating to social, economic and political issues. Information is available through their own reports, expert commentaries and analysis, blogs and videos. Examples include: The Adam Smith Institute, the Fabian Society, Demos.

Websites of professional bodies and organisations (and societies) are a good source of grey literature such as reports and bulletins. Many organisations also provide details of the latest research in their area. These are usually found on search engines such as Google.
They can also be a source of primary research as many list their own publications which may not be available through the databases you search.
Check our Subject Guides for lists of websites which may relate to your research question.
Many charities undertake research and produce their own bulletins and reports.
Again, you can check our Subject Guides for relevant websites. These resources allow you to search for charities related to your research topic.
Social media is often used by professionals, academics and researchers to communicate and share ideas. You can use social media to find information from resources such as blogs, podcasts, forums and reviews.
