Somewhat to aid the weakness of my memory and to assist her great
defects; for it hath often been my chance to light upon books which I
supposed to be new and never to have read, which I had, not
understanding, diligently read and run over many years before, and all
bescribbled with my notes: I have a while since accustomed myself to
note at the end of my book (I mean such as I purpose to read but once)
the time I made an end to read it, and to set down what censure or
judgement I gave of it; that so it may at least at another time
represent unto my mind the air and general idea I had conceived of the
author in reading him.--MONTAIGNE.
