Information helps you to see that you're not alone. That there's somebody in Mississippi and somebody in Tokyo who have wept, who've all longed and lost, who've all been happy. So the library helps you to see, not only that you are not alone, but that you're not really any different from everyone else.
As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value than a much smaller amount if you have not thought it over for yourself.
If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read.
