Step-by-step explanation:
In a library, catalogs are primarily used for identifying and locating books (print or electronic) and other materials in a particular library's collection. The catalog provides information about the items in the library's collection, such as the title, author, call number, and availability status. It helps users easily find and access the resources they need.
For example, if you are looking for a specific book in a library, you can search the catalog by title, author, or keyword. Once you find the book you are looking for, the catalog will provide the call number, which corresponds to a specific location on the library shelves. By following the call number, you can locate the book in the library.
Therefore, the correct answer is c) Catalogs.
