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.
Quand j'étais étudiante - c'était avant que les gens aient un large accès à Internet - pour écrire un article de recherche, je devais aller physiquement à la bibliothèque, et s'ils avaient le bon livre, parfait.
