In this quote, Faber is trying to explain that the details, ideas, and underlying information can be found in other sources besides books. He expressing that the information and ideas are the important part rather than the books themselves. The ideas can be found in a number of other outlets and venues. The book itself does not matter. Although, books are wonderful and unique, it is the idea the words on the page express and not the form of expression that matters. He even goes on to say "books were only one type of receptacle" and "there is nothing magical in them at all".
