What type of sources does a bibliography usually reference?

A bibliography typically includes academic texts and references utilized in scholarly writing, making it essential for providing credibility and context to the material presented. It serves as a way to acknowledge the sources of information that contributed to the research or analysis within a written work. These sources can include books, journal articles, theses, and other scholarly publications, which are key for supporting the arguments and claims made in the text.

While primary sources, such as interviews or documents from the time being studied, can be important for detailed research, they are not the sole focus of a bibliography. Similarly, personal diaries and anecdotes, although they can provide unique insights, do not encompass the broader scope of rigorous academic sources. All forms of media, including visual aids, may supplement research but aren't typically categorized under the scholarly references that a bibliography emphasizes. Thus, focusing on academic texts aligns with the purpose of bibliographies in scholarly work.
