A bibliography is a list of sources—books, articles, websites, interviews, and other materials—used or consulted when researching and writing a paper, report, or other work. Bibliographies give credit to original sources, allow readers to verify information and explore topics further, and demonstrate the breadth and quality of research. Academic and professional standards require proper citation of sources to avoid plagiarism. Different citation styles (MLA, APA, Chicago, etc.) specify how bibliography entries should be formatted. Learning to create proper bibliographies is an essential research skill taught in Canadian schools.
