### Miscellaneous earlier papers

Below are preprints of earlier papers for which I was able to find old files
that I could still make run under groff. There are also scans of a few
requested papers that I believe are now in Open Archive, since it has been at
least 20 years since they were published. In particular, I occasionally
receive requests for old papers on interval number of graphs:
#42,34,21,18,15,13,5. Nevertheless, when I still have a
preprint I will post that and not a scan or pdf of the published version.
