Academic research about policy topics is done across many different disciplines, and you may need to look in more than one discipline-specific database to find research on your topic.
These databases cover federal government documents. For Virginia government documents, you will likely need to use Virginia state government websites.
Gray literature is written by scholars or practitioners with expertise in the field of public policy, but not published in traditional academic journals.
Examples include white papers, reports, and proposals from think tanks and other public policy organizations. Gray literature can be very useful in finding policy alternatives or getting background information on a policy topic.
