I was so pumped back then, when I learned where the book scanner in my university’s library was located. Although I never needed it for class itself, when you need to write some papers and needed some literature - just go to the library, get the book, put it on the scanner, copy all chapters you need and then rinse and repeat with the next book. No need to carry a fuckton of paper home to cite from or work for hours in the library. A single pen drive is enough for that.
