Answer:
It is true: the card catalog lists books by subject, author, and title. The statement is correct.
Step-by-step explanation:
In order to make it easier for people to find a specific book, the card catalog organizes the books by subject, author, and titles. That is why it is so common to see those cards in the libraries, otherwise it would be very difficult to find something among so many books from different genres, authors, themes, and even titles, since some books can share the same title.
