I have had some success finding new vendors of older Films Inc titles on
the web. In addition to that, I did an Alta Vista search for one of your
titles I thought would be findable, Joan Jonas's Vertical Roll, and
found that Electronic Arts Intermix (http://www.eai.org/) carries it. So
I will bet that web browsing will yield vendors for at least a few of
your other titles.
