Etymologically, the word bibliography comes from the Greek “biblion”, which means “book” and “graphein”, which means “to write”. Its definition can be understood in two ways: the first concerns the list of a set of texts, used as consultation tools in the preparation of a written or research work. In this case, the bibliography concentrates the publications of greatest interest, related to the topic to be investigated, representing an important element at the beginning of an investigation.
Bibliographies are worth scientific, academic and monographic research works, as they indicate the author’s concern to seek sources that can support the bases of his research, in the same way that they serve as guidance and value addition.
The bibliographies are usually located at the end of the book, they aim to show the documentary support that the research had, in this way readers will be able to observe the repertoire of texts consulted by the writer, and which can serve as a reference for the analysis of a particular theme.
On the other hand, the term bibliography is used to define the science that is dedicated to the analysis of the description and orderly classification of books and other written materials. There are different types of bibliography, all aimed at the same research element that can be a book, disc, movie, etc. The bibliography is divided into:
Analytical bibliography is the one that details documents as bibliographic units, among them are: descriptive, in charge of exhaustively knowing the techniques and materials used in the publication of certain material.
The historical one is responsible for the study of the origins of the book, its first publications, etc. and the textual, is the one that applies the principles of analytical bibliography for the interpretation and modification of a text.
Enumerative or systematic bibliography, aims to gather information about individual texts or other graphic materials, within a logical and appropriate order, books are not seen as physical objects, but as intellectual entities. These bibliographies, in turn, are classified into: author bibliographies; bibliographic catalogues, literature guides, thematic, national bibliography, selective bibliography and universal bibliography.
