Every tale on this shelf reaches us through a decision by somebody to record it: an anonymous compiler working in the script of clerks, a parlour game that required a hundred strange things a night, a philosopher who set the beliefs down exactly in order to be rid of them, a civil servant who promised to change not one word, a foreign writer who named two of his sources and not the rest. These notes are about the records themselves — who made them, what they were for, and what each one leaves out.
