Just a joke (sort of). In 1987 when I was teaching at Columbia University, I had two computers in the room, projecting in different directions, and chalk boards. So I could have OCLC in one, a word processor in the other, and make notes to emphasize my lecture on the board. This past week, after 16 years at LIU, I finally had that functionality. Just in time to leave. What comes around goes around.
