Definition: The word "encyclopaedia" means a collection or compilation of information, often from different sources. It refers to a large body of knowledge about a particular subject, such as history, science, philosophy, art, etc. The term "Bibliography" is often used for this purpose. A bibliographic entry is a list of the works cited in an encyclopedia. For example, if you wanted to know what the most famous person from the 19th century was, you would search for "encyclopaedia bibliography 1800-1899", which would provide information on the works of famous people between 1800 and 1899.
