Before diving into the specific 1988 edition, it is crucial to understand the publication. The Nautical Almanac has been published jointly by the U.S. Naval Observatory (USNO) and Her Majesty's Nautical Almanac Office (HMNAO) in the UK since the 19th century.
It provides tabulated daily positions of the Sun, Moon, navigational planets, and 173 stars. A navigator uses a sextant to measure the angle between a celestial body and the horizon. By comparing that reading with the almanac’s data, they draw a "line of position" on a chart.
Without the almanac, a sextant is just a very expensive protractor.
