"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.

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...
