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.
Zu meiner Schulzeit -- also bevor man umfassenden Zugang zum Internet hatte -- musste ich zur Erstellung einer Facharbeit tatsächlich in die Bibliothek gehen, und wenn sie das Buch hatten, alles gut.
