Bibliographic notes: It appears that the version of the commentary that appeared on Usenet and has been transformed variously is just the notes. So far as I can tell, it's an accurate rendition of them. There were ~2 original versions of the two-volume work (the source and the commentary). The two versions are-- Those produced at UNSW: the one I have are in red (source) and orange (commentary) covers. There might have been more than one printing of this. The commentary was probably done on some nice terminal like the Diablo daisy-wheel. The source was rendered on a dot-matrix terminal. The second version was done within AT&T/WECo for internal use, and could also be ordered by licensees--perhaps it was even included with a tape. Salus says these were no longer available by 1978. These have pale blue covers. The contents were, I believe, a photocopy of one of the UNSW renditions. The Peer-to-Peer edition (1996) is probably a photocopy of an AT&T version; it contains various labels that doubtless would have been in them. But they could have been stripped in from tape labels or somewhere. Perhaps Berny Goodheart would know about this part of the production process. The UNSW version I have has, on its title page for the source book, a paragraph that says "This document may contain information covered by one or more licenses...." and is noted by Lions as issued in June, 1977. The PtoP version of this page is in a different font, and has a splash label in printer font "This information is proprietary and is the property of Bell Telephone Laboratories, Inc...." It's noted by Lions as of November 1977, and marked "second printing." It would be nice to cajole PtoP into reprinting, although the combination of the TUHS V6 sources and the various renditions of the commentary contain most of the information (though without the heartfelt encomia).
