    Re: A quarter-millennium of almanacs
    From: David Pike

    The human computers working in England were busy bees in the year 1767 and after, and it wasn't long before they were five years ahead of the calendar. It's a bit of a puzzle that you can't buy a modern Nautical Almanac for a year five years ahead of the calendar today.

    Perhaps it was to do with the length of time before you could next visit a decent book shop.  E.g. Cook’s voyages from August 1768 3 years, 3 years, and 4 years. DaveP
