What is a bibliography?

A bibliography is indeed a list of books and other sources referred to in a scholarly work, typically compiled to serve as an appendix or a reference point for readers. This list helps to provide credit to the original authors and works that informed the research or writing process. It is essential for academic integrity and allows others to locate the sources for further reading or verification. By including a bibliography, writers demonstrate the depth of their research and give their work credibility within the academic community.

The other options describe different concepts, such as visual timelines or collections of articles, which do not define a bibliography. While primary source documents are valuable for research, they are not part of the bibliographic listing itself. Therefore, the definition provided in the correct choice aligns with the accepted understanding of what a bibliography entails in scholarly contexts.
