If you scroll down to the bottom of the page there is a link just below the grid area that has the zip files that WT Sharp is talking about. It's easy to miss if you don't look for it.

I'm still sorting through them now and I seem to have missed a few (4 of them in the middle somewhere, I think), so I will definitely go back and look for the zips.
Thank you, as always, WT!
the link Crich70 provided takes us to the full series on MobileRead Wiki - but they are the individual titles.
