Bibliographic references

The references are a detailed list containing the information sources that are cited in the text. These are located at the end of the text, and their arrangement depends on the style chosen for their writing. Bibliographic references styles elements

Bibliographic references can be made in different styles and each style has a set of rules. Some of the styles most commonly used by Spanish-speaking countries are APA, Harvard, and Chicago.

Within each style, there are differences in the way and the order in which the information is referenced, although there are data that cannot be omitted, such as the title, the author and the year of publication.

Within any document that uses citations from other texts, bibliographic references should be used to give credit to the source that is being cited. In this way, plagiarism is avoided and the merit of other authors is recognized.

What are bibliographic references for?

One of the reasons why bibliographic references are used is to give credit to the authors on whom the text is based, or from whom verbatim citations are taken. In this way, you avoid running the risk of penalties for fraud or plagiarism.

Likewise, given that academic works or any type of research to be carried out, need to be validated by a previous investigation, bibliographic references provide a greater degree of credibility and coherence to the work carried out.

Additionally, the use of bibliographic references serves to provide the reader with the possibility of finding the information to which reference is made, or to make known the previous work of other authors. That is why all references must be correctly mentioned.
