I wonder if such a letter would be available for posterity if it were written today. Technically the student has the right to see what letters are written about him, but most schools want the student to waive that right (if they don't already have a policy of discarding the letters after matriculation). I suppose I am merely deathly curious about the letter I had written before my transfer from the University of Washington (since I only had one instructor I really expected to know anything about me, and I never got to see the letter), as obviously nothing written about me will merit later revisiting. At least not yet.
