[ih] Does anyone have a copy of this?

[John Day]

I am looking for a copy of this paper:

R. Kahn, Communications Principles for Operating Systems. Internal BBN memorandum, Jan. 1972. Proceedings of the IEEE, Special Issue on Packet Communication Networks, Volume 66, No. 11, November 1978. (Guest editor: Robert Kahn, associate guest editors: Keith Uncapher and Harry van Trees)

I don’t know why the citation to the Proceedings of the IEEE was with the citation. The paper is not in that issue. The paper seems to be cited often, but finding a copy seems to be much more difficult. ;-)

I have consulted the BBN library, the Computer History Museum, and the Charles Babbage Institute. None of them believe they have a copy. I have sent an email to Bob, but so far no reply.

I am not sure where else to look.  Suggestions?

Thanks,
John Day
