Google. Google, Google, Google. I used have to go to the library for all my research for which I didn’t have the reference books at home, and I was forever buying reference books of one sort or another. God bless libraries, I hope we never let them die, they are essential to our civilization. But still, a few clicks from my desk and I’ve got a one-word answer or an entire book or scholarly article on the screen in front of me—how could you beat that?
