The National Archives has created a handy pdf of a complete listing of OSS personnel. This is convenient because the ARC records were a little hard to use. The list includes location (box, file) in the NARA stacks that can be used to pull the record.
The listing includes over 23,000 names. Is a relative on the list? How many academics can you spot?
