Marshall Kirk McKusick, William N. Joy, Samuel J. Leffler, Robert S. Fabry.  
"A Fast File System for UNIX", Technical Report CSD-83-147, July 1983.

Go to http://sunsite.Berkeley.EDU/NCSTRL/ and search for any of the authors.  
There's scanned-in versions of this technical report there (OCR-ed, TIFF, and 
GIF).

These are not *early* documentation, but there are a number of UNIX papers in 
the "Unix Research System Papers, Tenth Edition, Volume II".  ISBN 
0-03-047529-5.  "Unix Research System Programmer's Manual, Tenth Edition, 
Volume I", ISBN 0-03-047532-5, was a set of manpages for V10 UNIX.  There was 
actually a VAX running V10 UNIX at Bell Labs, Murry Hill, up until about 
August 1994...
