Closest I can find w/regard to Atlas was a site saying Rand's books have sold over 20 million.

Can't find figures for Witnesses.

Left Behind claims 60 million for series.

That sounds about right.

My point is large unit sales of books are suggestive that an author's works are influential; but not a guarantee.

20 million sold and 1 million read completely.
