An encyclopedia is a comprehensive and authoritative source of information on various topics and an important reference book. Traditional encyclopedias contain articles or entries written by experts based on past studies, with detailed and systematic explanations. An encyclopedia is useful when you want to learn more about a specific person, event, object, theory, technique, definition, or history.  Perhaps you’ve heard of the  Encyclopedia Britannica, but did you know the Encyclopedia of Life (EOL)?
