A) Look up the subject in the library catalog
Nowadays there are millions of books on different subjects and content. Therefore, looking through the alphabetized shelves and periodicals when searching for a book may be exhausting, and would take some time.
With the library catalog, we can save time and go directly to the book we want. The library catalog is the option more efficient and effective when looking for a specific subject, such as ancient Egypt, as this tool provides the full stock of the physical library and their locations and elements (such as author, title, subject, bibliography, etc.), which makes it more easier to locate one particular book in a less than a minute.
