An encyclopedia is a reference work or compendium, usually in the form of a set of books, that provides information on many subjects or on many aspects of one subject. They are often divided into articles or entries that are arranged alphabetically by topic or article name.
A traditional almanac is an annual publication containing a calendar of predicted astronomical and meteorological data for a given year, including weather forecasts, farmers' planting dates, phases of the moon, tide tables, sunrise and sunset information, and other phenomena. Other almanacs may contain world records, population statistics, holiday and religious information, or predictions about trends in fashion, food, home decoration, technology and lifestyle for the upcoming year.
