A bibliography is a list of sources that were referenced or consulted in the creation of a work, such as a book, article, or research paper. It typically includes details like the author's name, title of the work, publication date, and publisher. Bibliographies help readers locate the original sources and verify the information presented. There are different styles for formatting bibliographies, including APA, MLA, and Chicago styles. Each style has specific rules for how to organize and present the information. A well-structured bibliography enhances the credibility of the work and allows for further exploration of the topic.
