Homeland Security Digital Library
The Homeland Security Digital Library (HSDL) contains documents related to homeland security policy, strategy, and organizational management. The HSDL is sponsored by the U.S. Department of Homeland Security's National Preparedness Directorate, FEMA and the Naval Postgraduate School Center for Homeland Defense and Security. The documents come from many government and non-governmental sources including federal, state, tribal, and local government agencies, professional organizations, think tanks, academic institutions, and international governing bodies. Resources are selected and evaluated by a team of librarians and subject-matter specialists.
