There are many different citation styles to choose from but APA, MLA and Chicago are the three most commonly used in academic works.
APA (American Psychological Association) is typically used for the traditional sciences such as Math and Chemistry, while the MLA (Modern Language Association) style is used for humanities and social sciences topics such as Anthropology, Cultural Studies or Literature and finally, the Chicago Manual of Style is often used in Art and History topics.
