Dictionaries are most often collections of words in one or more specific languages, usually arranged in alphabetical order, providing information like word meanings, usage, etymology, and, when they contain more than one language, translations. Some dictionaries include information more commonly found in encyclopedias. Encyclopedias are collections of information on terms, figures, eras, locations also arranged alphabetically, and, alongside definitions of terms, they also include more in-depth general information on a topic. Encyclopedias can be general or subject-specific.
Reference resources like Handbooks, Guides, and Manuals provide subject-specific, sometimes technical information to aid in understanding important aspects of the discipline or subject that they treat. Finding Aids are useful for finding information within libraries, archives, or specific collections.
Biography provides a description of a person's life, detailing the basic facts like birth and death, education, family background, etc. but also portraying the individual subject's experience of those life events.
