Bibliography
Writing a research paper or a thesis, you may encounter some references or some links below or at the very end of the page. We call these annotated bibliographies, or just bibliographies.
What Is a Bibliography?
A bibliography is a list of information that is usually found below the pages or at the end of the pages of a book, a research paper, a thesis paper, or even a report. The bibliography as the term itself is another word for listing your sources.
Bibliography Formats
Creating a bibliography is essential for any academic work to credit sources used. The format varies based on the citation style. Below are examples for the most common styles: APA, MLA, and Chicago.
