Each crop stands at the decade of the first year its book's date gives; a date given only as before a year stands at that year. Dates come from the catalogues and editions cited with each record. The bars draw the whole span and their counts to scale; in the strip below them, fifty years or more with no crop are folded and marked. Japanese dates converted with HuTime ↗
