I will be mailing the Unix TMs and other papers
to Robert Swierczek <rmswierczek(a)gmail.com>
who said he will scan any one-of-a-kind items
and make them available to you and TUHS.
After an embarrassingly long time, I have found a few spare cycles to
scan some of the more interesting items from Mel's collection. Many
of the papers can already be found online, others can be found with
slightly different formatting or missing the abstract. I will try to
prioritize accordingly:
