I think you are misunderstanding something.  A page from a book is still
copyrighted even if it is torn out of the book; the presence of the
copyright notice only in the front of the book, rather than on every page,
is irrelevant.  Putting a copyright notice in every file is common, but it
is a precaution, not a legal necessity, as I understand it.
