An important step in writing an essay is researching the contents you wish to develop. Bibliography is the base for that labor. Its objective is to broaden the criteria, contrast views, and acknowledge the discussion’s background or records regarding a topic. Nevertheless, we are not looking for a founding criterion. To this respect, José Luis Gómez indicates that (1976):
For example, the true essay writer, in some special occasions will make use of the page footnotes, and this takes us to the core of our topic: citations, numerous in essays, have their own value in relation to what the essay writer is trying to communicate; it is important to highlight that someone came up with an idea, noted in the citation, but the “who” and the “where” lack of value. Citations are not important because an author mentioned them, but rather because they are efficient. The fact that citations are mentioned is with the intention to indicate that they are not on their own, but rather, form part of a cultural background that is being reviewed.
Ideas derived from bibliographies may be important, however, it must first be important for the essay writer. Therefore, base plan and revision must allow the drafting of ideas to illustrate, contrast, and compare ideas written by other authors.
