The U.S. National Archives and Records Administration, Access to Archival Databases (NARA AAD) maintains searchable collections of government records and indexes online. The most popular are military: World War II Army Enlistment Records, Records on Korean War Dead and Wounded Army Casualties, Records of World War II Prisoners of War and Records with Unit Information on Military Personnel Who Died During the Vietnam War. The NARA AAD also has an index of historical Securities and Exchange Commission public companies – searchable by officer and director names and company names. This supplements (although the NARA doesn’t have the documents online) the free full text search in the EDGAR system at the SEC (which is only the past 4 years) and the header information in SEC filings (which goes to 1994).
