It has been a December tradition for me to pick up the Nautical Almanac for the next year (and Eldridges for tides,  Merry xmas to me,LOL).  I Prefer the hardcover for nostalgic reasons of real books, but usually pick up the Blue Softcover Commercial edition, readily available at local haunts like West Marine, Landfall, and Defender.

I noticed prowling Amazon the other day there is a long term Alamanac, hypothetically good till 2050.  Which exceeds my probable life span.

I assume that it is an Almanac with corrections, such as we might do if faced with using an expired almanac a year or two old in an emergency.

Am i right?, does this add a step and yet a new place for possible distracted error? is it worth my while?  I am kind of fond of the tradition of my New Almanac each year for reasons of emotion not logic. 

The Long Term Almanac is attractive, for reasons of cost, and a sense that I'm always prepared.

I can see an advantage to the boat world traveler who might have reason to get several years ahead, but to me, who is tied to the East Coast for the moment, it hardly seems a worry.
