Literature

Literature, a body of written works related by subject‐matter (e.g. the literature of computing), by language or place of origin (e.g. Russian literature), or by prevailing cultural standards of merit. In this last sense, ‘literature’ is taken to include oral, dramatic, and broadcast compositions that may not have been published in written form but which have been (or deserve to be) preserved. Since the 19th century, the broader sense of literature as a totality of written or printed works has given way to more exclusive definitions based on criteria of imaginative, creative, or artistic value, usually related to a work's absence of factual or practical reference. Even more restrictive has been the academic concentration upon poetry, drama, and fiction. Until the mid‐20th century, many kinds of non‐fictional writing—in philosophy, history, biography, criticism, topography, science, and politics—were counted as literature; implicit in this broader usage is a definition of literature as that body of works which—for whatever reason—deserves to be preserved as part of the current reproduction of meanings within a given culture (unlike yesterday's newspaper, which belongs in the disposable category of ephemera).

Poem 

A poem is commonly defined as a composition written in verse (although verse has been equally used for epic and dramatic fiction). Poems rely heavily on imagery, precise word choice, and metaphor; they may take the form of measures consisting of patterns of stresses (metric feet) or of patterns of different‐length syllables (as in classical prosody); and they may or may not utilize rhyme

 Drama 

 A play or drama offers another classical literary form that has continued to evolve over the years. It generally comprises chiefly dialogue between characters, and usually aims at dramatic / theatrical performance (see theatre) rather than at reading. During the eighteenth and nineteenth centuries, opera developed as a combination of poetry, drama, and music. Nearly all drama took verse form until comparatively recently. Shakespeare could be considered drama. Romeo and Juliet, for example, is a classic romantic drama generally accepted as literature.

 Essay

'Essay' in English derives from the French 'essai', meaning 'attempt'. Thus one can find open‐ended, provocative and/or inconclusive essays. The term "essays" first applied to the self‐reflective musings of Michel de Montaigne, and even today he has a reputation as the father of this literary form.

 Prose 

 Prose consists of writing that does not adhere to any particular formal structures (other than simple grammar); "non‐ poetic writing," writing, perhaps. The term sometimes appears pejoratively, but prosaic writing simply says something without necessarily trying to say it in a beautiful way, or using beautiful words. Prose writing can of course take beautiful form; but less by virtue of the formal features of words (rhymes, alliteration, metre) but rather by style, placement, or inclusion of graphics. But one need not mark the distinction precisely, and perhaps cannot do so.
