    Congressional Research Service Reports

    Congressional Research Service reports can be the best way to quickly get up to speed on major political issues. CRS is Congress’ think tank, and its reports are relied upon by policymakers and others for accurate, timely and nonpartisan analysis of important policy issues

    In partnership with a Republican and Democratic member of Congress, includes reports available on Congress's internal website, more than eight thousand in all. 
  • Library of Congress
    The Consolidated Appropriations Act of 2018 directs the Library of Congress to make CRS reports publicly available online. The result is a new public website for CRS reports based on the same search functionality that Congress uses – designed to be as user friendly as possible – that allows reports to be found by common keywords. Moving forward, all new or updated reports will be added as they are made available to Congress. The Library is also working to make available the back catalog of previously published reports as expeditiously as possible.
