Literature is any collection of written work, but it is also used more narrowly for writings specifically considered to be an art form, especially prose, fiction, drama, poetry, 

 a body of written works. The name has traditionally been applied to those imaginative works of poetry and prose distinguished by the intentions of their authors and the perceived aesthetic excellence of their execution. Literature may be classified according to a variety of systems, including language, national origin, historical period, genre, and subject matter.

For historical treatment of various literatures within geographical regions, see such articles as African literature; African theatre; Oceanic literature; Western literature; Central Asian arts; South Asian arts; and Southeast Asian arts. Some literatures are treated separately by language, by nation, or by special subject (e.g., Arabic literature, Celtic literature, Latin literature, French literature, Japanese literature, and biblical literature)

The scope of literature

Literature is a form of human expression. But not everything expressed in words—even when organized and written down—is counted as literature. Those writings that are primarily informative—technical, scholarly, journalistic—would be excluded from the rank of literature by most, though not all, critics. Certain forms of writing, however, are universally regarded as belonging to literature as an art. Individual attempts within these forms are said to succeed if they possess something called artistic merit and to fail if they do not. The nature of artistic merit is less easy to define than to recognize. The writer need not even pursue it to attain it. On the contrary, a scientific exposition might be of great literary value and a pedestrian poem of none at all.

The purest (or, at least, the most intense) literary form is the lyric poem, and after it comes elegiac, epic, dramatic, narrative, and expository verse. Most theories of literary criticism base themselves on an analysis of poetry, because the aesthetic problems of literature are there presented in their simplest and purest form. Poetry that fails as literature is not called poetry at all but verse. Many novels—certainly all the world’s great novels—are literature, but there are thousands that are not so considered. Most great dramas are considered literature (although the Chinese, possessors of one of the world’s greatest dramatic traditions, consider their plays, with few exceptions, to possess no literary merit whatsoever).
