  DESCRIPTION  Central files at ORNL consist of multiple series 
               maintained at a single location in the  Laboratory 
               since its inception. This central filing unit has 
               provided individual document  control and 
               currently serves as a report clearance mechanism. 
               This series is a master  file for ORNL reports in 
               all areas of research and development. There are 
               approximately 75 different prefixes for reports in 
               this file; each relates to a specific topical  
               area. ORNL prefixed reports, for example, are 
               official institutional reports, while MON  reports 
               were generated by Monsanto Corporation when it 
               operated the laboratory.  Various indexes are 
               available. The DOE Office of Scientific and 
               Technical Information  (OSTI) indexes the reports 
               from 1974 forward. 
 
  RESTRICTIONS   This series contains a small amount of 
classified information.
