Libraries

All written knowledge was made accessible through libraries.

Over time libraries expanded to store more and more information. From the Library of Alexandria that had 1 million papyrus scrolls to the New York Public Library that has 10 million books.

If you read 1 book per week for your entire life, at the end you'll have read a few thousand books. That's less than 0.1% of what's available in a modern library. The trick is to know which books to read.
