Books are not sealed after the 13 days, but only the author (or the editor one is assigned) can checkout the original and only the original can be copied.

Now, I don't have much of a problem with some sort of mechanic that allows the author to deny or allow general copying rights to the Librarian after the year long lock is over. I just don't want any such thing to be automatic.

There kind of is a choice already as far as publication and distribution goes. If a book is archived only, then it stayes in your library. It doesn't go out to the rest of them. Then the Librarian can put it on the restricted access shelves and only folks with restricted library card acess can get to them. That said, the Library would lose out on the culture weight that publishing your book would have granted and I can't see too many Librarians being willing to spend the 10,000 gold to archive books that don't benefit the Library at all. If you don't want your book distributed in the Library, best just not to give it to a Library in the first place.
