Back when I was in school, this is before people had wide access to the internet, if I was going to do a research paper, I would have to physically walk to the library, and if they had the book that you needed, great. You sometimes had to send out for it, so the process could take weeks.
Cuando era estudiante, antes de que la gente tuviera acceso amplio a Internet, para escribir un informe de investigación tenía que ir físicamente a la biblioteca. Si tenían el libro que querías, perfecto, pero tenían que pedirlo a otro sito a veces, y el proceso podía tardar semanas.
