I am just on the verge of tossing the big decks of index cards I made for papers I wrote 25 years ago. The charm they have as artifacts of a bygone era is outweighed by the space they take up. (Maybe someone here wants 'em? They’re yours for the price of shipping.)
Back then we were still slightly uncertain about how to even cite Internet sources. I have no idea how teachers even began to weather what was shortly to emerge.
