NARA Captured German Documents
 


 
U.S. National Archives & Records Administration
 
The U.S. National Archives & Records Administration (NARA) provides one of the best resources for original German documents.  Information on their Collection of Foreign Records Seized (Record Group 242) can be found here: http://www.archives.gov/research/captured-german-records/index.html.  Most will be interested in the Captured German Records Microfilmed at Alexandria, Virginia, USA and information on this set of records can be found here: http://www.archives.gov/research/captured-german-records/foreign-records-seized.html#virginia
 
There are guides to the records and since there are thousands of microfilm rolls finding what you are looking form without the guides is almost an impossible task.  The link above has some information on which guides are available and in what publication they can be found.
 
The guides to German Records Microfilmed at Alexandria, Virginia can be found on this site at this link: Guides to German Records.
