Yes!  Many on another platform where they are quite active are correct in noting this can be explained by sorting info and how their algorithm works.    I remember some of these books being referenced and certainly some of these topics, but not all of the books.  It is truly fascinating.  Came upon some other results in another search and am trying to gather that info. What I believe They have not done, is poked around just a little more meticulously into what is actually Contained in those books.  They should do so themselves, but. . .they takes a Great Deal of Time and Patience.  We live in a society of. . .We Want it Now.  As you already know, doesn't happen that way!
