One of the important reasons for citing your sources is to provide readers with enough information so they can track down the sources you used to support your research.
Considering this reason for citing your sources, all citation styles require the same basic elements, which include: author or author names, title of the article or chapter, title of the book or journal or source of the article, editor, edition number, publisher, publication year, volume, issue, and location.
Different citation styles exist because scholars and researchers of different disciplines prioritize the types of information differently and therefore create citations that reflect those priorities.
