LOL That’s a pretty limited ‘literacy’.
Not necessarily, again.
Classical books is an interesting and difficult term to define.
From Wiki on Classical books, “A classic book is a book accepted as being exemplary or noteworthy, either through an imprimatur such as being listed in any of the Western canons or through a reader’s own personal opinion.”
Notice even, “a reader’s own personal opinion”.
There is a link that defines a more classical definition of classical that is referred to as the “Western canon.” And then there is another definition which is referred to as “Great Books.”
If we wanted to refer to the modern classical books, then that would refer to what time period exactly? Even that could be difficult to state. Although there is generally acceptable classical definition of modern classical books.
