What type of resource is an encyclopedia?

An encyclopedia is defined as a comprehensive reference work that provides detailed information on a wide range of topics, presented in an organized manner, often arranged alphabetically. This resource is designed to summarize knowledge from various fields, making it a valuable tool for research and learning. The format allows readers to quickly find specific information on various subjects, covering everything from science and history to culture and geography. This characteristic makes it distinct from other types of resources, such as collections of fictional stories, literary guides, or historical narratives, which serve different purposes and have different structures. Thus, the correct characterization of an encyclopedia aligns closely with its primary function as a broad informational resource.
