The original High Sierra spec was published by NIST (formerly NBS) and is 
available from

  NISO/NIST
  Administration 101
  Library E-106
  Gaithersburg, MD 20899
  (301) 975-2814

What you really should be looking at is the international standard which 
is equivalent to High Sierra; ISO 9660 (also known as ECMA-119 or 
pANS Z39.60 198x).  This is (probably) available from the same source, or
write to the International Organization for Standardization in Geneva,
Switzerland.  (Sorry, I don't have a better address than that.)

These documents are written in bureaucratese.  For a human-readable 
description of High Sierra, look in the second Microsoft CD-ROM conference 
book.

High Sierra/ISO 9660 is a operating system independent volume format.  It 
specifies directory and file structures in a way such that the CD is 
readable under a variety of operating systems.  Support is provided by 
many operating systems, including Apple Macintosh, Apple IIgs, MS-DOS, 
Digital's VMS, and many varieties of Unix.

Note that High Sierra defines how to get to the files, not the file 
contents.

If you have further specific questions, ask. I wrote the Mac High 
Sierra/ISO 9660 drivers.
