What is MLA?
MLA, or Modern Language Association, is a widely used style guide for writing and documentation in the humanities, especially in disciplines such as literature, languages, and cultural studies. It provides guidelines for formatting papers, citing sources, and creating a Works Cited page.
Citation Style
MLA style uses parenthetical citations within the text to refer to sources, including the author’s last name and the page number(s) from which the information was taken. For example, (Smith 123). These citations are brief and allow readers to easily locate the corresponding entry in the Works Cited list at the end of the paper.
Works Cited Page
The Works Cited page is a separate section at the end of the paper where all sources referenced in the text are listed alphabetically by the author’s last name. Each entry includes essential bibliographic information such as the author’s name, title of the source, publication date, and other relevant details. The format varies depending on the type of source, such as books, articles, websites, and more.
Formatting Guidelines
MLA also provides specific formatting guidelines for the overall layout of the paper, including margins, font size and style, spacing, and headers. Papers in MLA style are double-spaced and formatted with a legible font such as Times New Roman in 12-point size. Additionally, MLA recommends using headers with the author’s last name and page number at the top right corner of each page.
Updates
MLA style is periodically updated to reflect changes in research practices, technology, and publication standards. It is essential for writers to consult the latest edition of the MLA Handbook or refer to reputable online sources for the most current guidelines and examples.

What is Chicago?
Chicago style, also known as The Chicago Manual of Style (CMOS), is a comprehensive style guide that provides rules and guidelines for writing and citation in various disciplines, including history, literature, and the arts. It offers two main citation formats: notes and bibliography and author-date. Chicago style is widely used in academic writing, publishing, and professional fields.
Citation Formats
- Notes and Bibliography:
- This format uses footnotes or endnotes to cite sources within the text, providing additional information or commentary.
- Each citation corresponds to a superscript number in the text, which links to a footnote or endnote containing bibliographic details.
- The full citation is then listed in a separate bibliography section at the end of the paper, arranged alphabetically by the author’s last name.
- Author-Date:
- In this format, parenthetical citations are used within the text, including the author’s last name and the publication year.
- These citations direct readers to a corresponding entry in the reference list, which is placed at the end of the paper and organized alphabetically by the author’s last name.
Usage and Flexibility
Chicago style offers flexibility in citation styles and formats, allowing writers to choose between the notes and bibliography format or the author-date format based on the requirements of their discipline or publication. This versatility makes Chicago style adaptable to various academic and professional contexts.
