Congressional Research Service reports

The Congressional Research Service, an arm of the Library of Congress, provides Congress with non-partisan and in-depth legislative research and analysis on a variety of topics. The CRS produces more than 3,000 studies and publications each year, none of which are distributed to the public. The Thurgood Marshall Law Library has created an online collection, called the Congressional Research Service Reports Collection, in the subject areas of Homeland Security/Terrorism and Health Law and Policy. Examples of some recently added titles (with publication dates):
Congress's Contempt Power: Law, History, Practice, and Procedure 7/24/07
Extraterritorial Application of American Criminal Law 9/10/07
Presidential Claims of Executive Privilege: History, Law, Practice & Recent Developments 9/17/07
U.S. Arms Sales to Pakistan 11/8/07
The collection can be browsed by subject area or date.
