MLA
MLA citation style is most frequently used in the humanities (literature, languages, art). The MLA Handbook was first published by the Modern Language Association in 1951.
MLA style relies on parenthetical citations (author, page number) for material that is quoted, summarized or paraphrased in the text of a paper. The sources referenced in parenthetical citations are compiled at the end of the paper as a Works Cited list.

Chicago
Chicago style is most frequently used within the field of history, although it is used by other humanities-based disciplines as well. The first edition of the Manual was published in 1906 by the Unversity of Chicago Press.
Chicago style offers two options for in text documentation:
1. Superscript numbers within a paper to designate paraphrased, summarized, or quoted material, which correspond to footnotes or endnotes that specify the author, title, and page(s) cited.
2. (Author Date) parenthetical citations within a paper to indicate paraphrased, summarized or quoted material.
In both cases, the Bibliography at the end of the paper includes full citations for all sources referenced in a paper. In addition, it may include sources the writer consulted but did not paraphrase, summarize or quote.

CSE
CSE style is commonly used in the sciences. The first edition of the style manual was published in 1960 by the Council of Biology Editors (renamed the Council of Science Editors in 2000).
CSE style offers three options for in text documentation:
1. (Author-Year) parenthetical citations within a paper to indicate paraphased, summarized or quoted material.
2. Citation-Sequence with superscript numbers to designate paraphrased, summarized, or quoted material, which correspond to numbered (nonalphabetized) entries in the references list at the end of a paper.
3. Citation-Author is based on alphabetized, numbered references at the end of a paper. The corresponding in text citations are designated by superscript numbers.
The organization of the References list at the end of the paper varies, depending on which in text documentation method the writer follows.
