In an ER diagram for a library, the relationship between authors and books typically allows for tracking of authors regardless of the number of books they've written. The statement that we cannot keep track of authors that did not write any of the library books is true because, in most library systems, authors are only recorded in relation to their works. If an author hasn't written any books in the library's collection, there would be no record of them in the system.
