The roff(7) contains broken links. Namely, http://cm.bell-labs.com doesn't even exist any more.
The archive of the Bell Labs Journal and the technical reports seem to be available at https://www.alcatel-lucent.com/bell-labs-journals but I didn't go through the indiviudual references. (I did once, to download them, but that was before I read roff(7) now.) The Ossana paper is available at troff.org, but the other papers are linked (by troff itself) to the nonexistent http://cm.bell-labs.com .
