If you define "engine" as not having a book, then of course you can say, "A book
is not part of the engine." Unfortunately, the "engine" is only one part of the
program as a whole.

I think it's another discussion about whether or not it's ok to use opening
books or endgame tablebases that you didn't make, but these things, if created
by one of the program's authors, are a part of the program. If you want to
define the engine as only being the searching and evaluation part of the
program, fine. It's only a matter of using different terminology.
