Problem: Definitions of literature have varied over time; it is a "culturally relative definition". In Western Europe prior to the eighteenth century, literature as a term indicated all books and writing. A more restricted sense of the term emerged during the Romantic period, in which it began to demarcate "imaginative" literature. Contemporary debates over what constitutes literature can be seen as returning to the older, more inclusive notion of what constitutes literature. Cultural studies, for instance, takes as its subject of analysis both popular and minority genres, in addition to canonical works.
Due to the unvarying definition of literature, what can the term "literature' be described as?
