This "free, searchable database of federal government spending" from OMB Watch, "a nonprofit research and advocacy organization dedicated to promoting government accountability," is drawn "largely from two sources: the Federal Procurement Data System, which contains information about federal contracts; and the Federal Assistance Award Data System, which contains information about federal financial assistance such as grants, loans, insurance, and direct subsidies like Social Security." Includes a handy glossary. <http://www.fedspending.org/>
