The volumes shown below are available to anyone in need. I have no interest in Zubal Books, except as a customer.

For what it's worth... If you have not scrolled the website devoted to International Correspondence Schools recently... you may be surprised to find previously unavailable works. The site has expanded.

I had thought many volumes of the ICS study courses were also freely available on line as archive scans of older 'editions'.

Note the discussion here:

and

which indicates a DVD of all the volumes, with the approval of the putative current copyright holder, was in process by 2008 but ran into 'snags' by 2014. (I would also mention in passing that the Wildwood editions are dated 1979, one year after the copyright law was changed to require 'new' filing for older works after 1978...)

I believe a current listing of ICS archive titles is here:

A great many of the more 'interesting' booklets, including the mentioned 529B "Wheel, Rod, and Pin Work" are not yet available. (Note that they say they have 636-643, dealing with diesel locomotives circa 1945, but haven't scanned them yet...)

I got several volumes as photocopies from the Steam Automobile Club of America back in the days before Google Books. They probably aren't as nicely reproduced but provide perfectly good education.
