The literature in the ebooks is the art that uses the word as an instrument. For extension, it refers also to the set of literary productions of a nation, of an epoch or enclosed of a genre (the Greek literature, the literature of the XVIIIth century, the fantastic literature, etc.) and to the set of works that turn on an art or a science (medical literature, juridical literature, etc). It is studied by the literary theory in different e-books.
In the XVIIth century, what today we name «a literature« was designated like poetry or oratory in the books. During the Century of Gold, by poetry there was understood any literary invention, belonging to any genre and not necessary in poem. At the beginning of the XVIIIth century one began to use the word «literature« to refer to a set of activities that were using the writing as an expression way. In the middle of the same century Lessing, where «literature« is used to refer to a set of literary works like e-books. At the end of the XVIIIth century, the meaning of the term literature specializes, being restricted to the literary works of recognized esthetic quality. This concept can be in the work of Marmontel, Elements of litterature (1787), and in the work of book. In England, in the XVIIIth century, the word «literature« was not referring only to the writings of creative and imaginative character, but it was including the set of writings produced by the educated classes: they were fitting in her from the philosophy to the essays, happening for the letters and the poetry ebooks. It was a question of a society in whom the novel had bad reputation, and one was questioning if it had to belong to the literature. That’s why Eagleton suggests that the criteria to define the literary Corpus Christi in the England of the XVIIIth century were ideological, limited to the values and to the tastes of an educated class. There were admitted neither the street ballads nor the romances, nor the dramatic works. In the last decades of the XVIIIth century there appeared a new demarcation of the speech of the English society. Eagleton tells us that there arises the word «poetry« as a product of the human creativity in opposition to the utilitarian ideology of the beginning of the industrial age. We find such a definition in the work Defense of poetry (1821) of Shelley. In the England of the Romanticism, the “literary” term was synonymous of «visionary« or «creative«. But it was not stopping having ideological dyes, as in case of Blake and Shelley, for whom it transformed in political ideology, which mission was to transform the society by means of the values that were becoming incarnate in the art. As for the writings in prose, they did not have the force or the rooting of the poetry; the society was considering them to be a vulgar production lacking in inspiration in the ebook.
