" ''The Astronomical Almanac'' is the direct descendant of the British and American navigational almanacs. The British ''Nautical Almanac and Astronomical Ephemeris'' had been published since 1766, and was renamed ''The Astronomical Ephemeris'' in 1960. ''The American Ephemeris and Nautical Almanac'' had been published since 1852. In 1981 the British and American publications were combined under the title ''The Astronomical Almanac''."^[3]
