Definition of term:: Almanac

  • "A kalendar, usually in pocket-book (more rarely sheet) form, augmented with Saints’ days, fair-dates and astronomical and meteorological data; a bestseller from the start and protected by jealously guarded patents, the different titles, hot rivals in the 17th century, were all finally swallowed up by Dr Francis Moore’s Vox Stellarum, familiarly known as ‘Old Moore’s Almanack’." (Carter, ABC for Book Collectors)
