"

Definitions of literature have varied over time.[1] In Western Europe, prior to the 18th century, literature denoted all books and writing. It can be seen as returning to older, more inclusive notions, so that cultural studies, for instance, include, in addition to canonical works, popular and minority genres. The word is also used in reference to non-written works: to "oral literature" and "the literature of preliterate culture".[citation needed]
