Answer:
to have a book you can physically hold
Step-by-step explanation:
According to the professor in Fahrenheit 451, it was better to have a book that you can physically hold. He explained that nothing compares to the adventure of owning a physical book; from the moment you touch it, to the moment you open it and scroll through the pages to the moment you read the last words. For the professor reading books was an experience and he preferred physical books, because in that way he could experience the same story every time he wanted (every time he opened and read the book).
