<em>Option b. The library drawer-upon-drawer file that contains information about every book in the library is called the card catalog.</em>
Explanation:
A card catalog is a register of all bibliographic items that can be found in a specific library. It is a form that the librarians have to organize all of the items the library holds, so that they can be found in an easy and practical manner. Although the card catalog has been familiar to all library users for a long time, it is now being replaced, in the majority of the libraries, by an online public access catalog as a form of updating the service in a more modern way.
