The EXTRAS directory contains files which facilitate the use of the data on   
the disk, but which are not actually required for the use or understanding    
of those data.                                                                
                                                                              
CATALOG_FILES      Contains copies of the documents in /CATALOG               
                   renamed with a .TXT extension for easier use.
