The policy document data includes sources that are designed to change or otherwise influence guidelines, policy or practice.

Tracked policy sources and document types range from government guidelines, reports or white papers; independent policy institute publications; advisory committees on specific topics; research institutes; and international development organisations. We aim to curate a broad scope of policy sources from organisations around the world and cover topics from climate change to health, transport and economics. Policy sources are largely collected directly from organisations' publications websites and are updated regularly.

To see a complete list of sources covered in Dimensions, open “Analytical Views” while searching policy documents, and then go to the “Publishing organizations” tab. This will then list all of the sources found in Dimensions.
