When I was a kid we had the whole set. I assume that it was something tied together with Britannica -- we had an early 60's set. I tried to read them but the font faces were so small that they were terrible reading copies. If memory serves, I remember really, really trying to read Moby Dick and Darwin (are they both on the list?) but the tiny type and terrible formatting defeated me.
More than 45 years later, I've read maybe 70% of the books in the list (maybe more), but all in different, more readable editions. Today almost everything I read is in epub, and pdf for technical and scientific papers.
