Category MLA APA CMOS General Approach The Modern Language Association (MLA) provides a method for source documentation that is used in most humanities courses. The humanities place emphasis on authorship, so most MLA citation involves recording the author’s name in the physical text. The author’s name is also the first to appear in the “Works Cited” page at the end of an essay. The most recent MLA formatting can be found in the eighth edition of the MLA manual.

Note that the MLA 8th^ ed. extensively references the notion of a “container” in its instructions for formatting citations. In this context, a container is the larger work that contains the specific source (e.g., if a chapter is being cited, the book is its container). The container is normally italicized and followed by a comma.

The American Psychological Association (APA) provides a method for source documentation that is used in most social sciences courses. The social sciences place emphasis on the date a work was created, so most APA citation involves recording the date of a particular work in the physical text. The date is usually placed immediately after the author’s name in the “References” page at the end of an essay. The most recent APA formatting can be found in the sixth edition of the APA manual.

The Chicago Manual of Style (CMOS) includes two systems for citation: a notes and bibliography (NB) system and an author-date (AD) system. This poster displays citations in the NB system, which is used in most history courses. The primary difference between the two systems’ citations is that in AD, the publication year follows the author’s name.

History places great emphasis on source origins, so footnotes and endnotes are used to demonstrate on-page where a particular piece of information comes from. In the NB system, a number is assigned to a particular fact in the text, and the correlating footnote or endnote will link the source to the text and to the bibliography. The most recent CMOS formatting can be found in the seventeenth edition of the CMOS manual.

Reference Lists

Occasionally truncated entries are given simply to focus on the differences between citations for each type of material. Ellipses indicate which entries would normally continue according to the basic principles of each style. Please see the OWL’s Research and Citation section for more details. Citing Books Book citations in MLA generally require the author name, work title, publisher, and year published. Provide a publication city if the book was published before 1900 or there are two versions of a book (i.e. British and US edition).

Book citations in APA generally require author name, publication year, work title, publication city, and publisher.

Book citations in CMOS style generally require the author name, work title, publication city, publisher, and publication year.

Online Sources For most online sources, the MLA asks for author/editor, title, website title, publisher/organization, publication date, volume/issue number, page numbers, and URL. However, the URL should omit http:// or https://. Whenever possible, use a permalink or DOI (digital object identifier) instead of a URL. A date of access can also be helpful, especially if the source does not have a publication date.

In APA citation, online sources often include DOIs (digital object identifiers). If a DOI is available, it is used in place of a URL. The DOI is frequently found on the first page of an online source. APA generally cites author, date, page title, site title, available page numbers, and a URL or DOI.

CMOS citation requires the URL or DOI to be listed at the end of the citation. The date of access should also be included if there is no publication or modification date. Citations for websites should be included in the notes, and only included in the bibliography if there are no notes.

Titles of websites are usually set in roman (i.e., no formatting). However, titles of blogs, books, journals, shows, movies, and similar sources should be italicized. General format

In-Text Citations

Citing Books Like most source documentation systems, MLA uses in-text citations to give readers information and directs readers to the more specific Works Cited page should a reader want to pursue a source further. Generally, MLA in-text citation requires an author name and a page number where the information being cited can be found.

APA adds to MLA style by including page number(s) and date. The date is generally provided parenthetically next to author(s’) names, while page numbers always appear parenthetically at the ends of sentences. The date is important in social science because it helps demonstrate the relevance (newness) of the work being cited.

Footnotes or endnotes are used when citing within the text of a CMOS formatted document. Often a final bibliography is also included at the end of a text. Footnotes in CMOS style generally include the author name, the publication title, publication date, publisher information with the very first citation, and a page number.
