It is amazing to me how we even learned anything advanced back then. It was almost like we were so "dumb" compared to today's kids. The library and the bookstore at the mall (WaldenBooks) was my main staple as a young pre-teen kid. I'd never pass up a chance to go with my mom to either the library or the mall.
I remember as a 16yo trying to buy my first car (used 1979 Camaro) and how I thought knowing about the NADA guide you could browse through at the library was secret knowledge and used the copied page as negotiations tool. Now that info and more is readily available in few clicks on your portable phone/computer you carry in you pocket when at the dealer.
