This sub-series is similar to the personnel clearance files found in Series I, but these files are different and have consequently been kept as an independent series. The contract work these files deal with spans both the wartime and post-war periods. The folders have been kept in the order they were originally found (which at times seems to be loosely based on the contract numbers involved) as have the contents of the files. In addition to the usual preservation measures, most of the original file folders were photocopied to retain information about the contract number, found on the folder tab, or handwritten notes on the folder itself. Original file names were kept; new ones were created only if the original was non-existent or inappropriate to the contents. The majority of the files are personnel files. Contents include signed forms, letters of reference, fingerprints, tax information, salary information, grade lists, family and other personal information and termination notices. Interestingly, there are even personnel clearance records for construction workers and maintenance workers who had jobs in Pupin and other buildings where much of this top secret war work was taking place. In addition to personnel files, there are also files containing general lists for the various research groups, requisition forms (for both employees and materials), salary recommendation forms, blank forms used by the people involved in this work, salary lists, and a book listing badge numbers. Much of the materials appear to be associated with atomic research or the Atomic Energy Commission. Contract numbers referred to within these files are: AT-30-2-GEN-16 (subcontracts S-165 and S-162); EIDM MI-4 MS; EIDM I-1 CU; W7405-eng-50 (referred to very heavily); W-31-109 eng17; EIDM D-22; EIDM-AA-1 CU; AT-30-1 GEN-72; AT-30-1 GEN-70; W-31-109 eng15; AT-30-1-GEN-257; W-31-109 eng14.
