It is defined as a bibliographic reference to the conjunction of numerous data in a document or research that supports the information written in a monographic work, this is applied so that the professor in charge of the review knows where to look for said exposed information. in the content of the work carried out.
The parameters for the writing of a bibliographic reference will depend on the type of publication in which the document used is found (undergraduate work, reprint of a scientific journal, book, website, etc.); approximately the most common elements are: author, subject title, year along with the place of publication and pages where the information is found.
The data that should be included in a bibliographic reference usually appears on the title page or on the first page of the work, such as the name of the person who created the content and the publisher, the date of publication and the title. More information can be found on the credits or rights page, with legal information and the so-called International Standard Book Number (whose acronym is ISBN).
This cited ISBN may determine that it is a single-type bookmark that is used for books and currently consists of a total of thirteen digits, replacing the ten previously used. Ten digits that were divided into four clearly delimited blocks that made reference to what was the code of the country or the language of origin in which the book was written, the publisher, the article number and finally the relevant check digit.
Not all the information obtained should be cited in the bibliographic references. Therefore, if the original source is a letter, an email, or an informal conversation, all these references should not be part of the bibliography.
Although each country has its own tradition and methodology in the development of bibliographic references, in recent years the international ISO standard for publications has become widespread. It is a logical and reasonable process, since in this way a standardization is achieved that facilitates access to information and knowledge.
