Chicago 17 Notes and Bibliography is a numbered style, meaning in-text citations are represented by superscript numerals like this1 and this,2 that correspond to numbered footnotes at the bottom of the page containing the citation details. All citations are then listed in an alphabetically ordered bibliography at the end of your assignment.

HIDDEN Style rules

Placement of reference numbers (superscripts) within the text

Citing a source in-text should follow a basic referencing principle which is to distinguish between ideas or words borrowed from others and those of your own.

Insert the reference number right after stating a borrowed idea or direct quotation, which is not necessarily at the end of a sentence. A hypothetical example:

This sentence shows two superscript numbers to indicate acknowledgement of an idea from one source,1 and of another from a different source.2 An exception to the rule of placing the reference number after a punctuation mark is the dash or hyphen: the superscript should be placed before the dash or hyphen, like this3—note that there is no space between the superscript and the dash. The superscripts then correspond to numbered footnotes at the bottom of the page or endnotes at the end of the entire text depending on which type of notes you are required to use.

Here's how to insert footnotes and endnotes in Word for Office 365, Word 2019/2016/2013/2010/2007.

General formatting rules for notes entries
  • There are two types of notes: footnotes which appear at the bottom of the page, and endnotes which appear at the end of an article (but is not the same as the bibliography list). Confirm with your course convenor whether they require footnotes or endnotes.
  • Provide a full note entry the first time a source is cited; subsequently, use the shortened form. This guide shows the first full entry and the shortened note for most of the examples by source.
  • Chicago 17 discourages the use of ibid. Use the shortened note even when citing the same immediately preceding source.
  • Notice that citation elements in note entries are separated by commas, whereas in bibliography list entries, elements are separated by full stops.
Bibliography list general rules
  • The bibliography list starts on a new page at the end of the essay, with the heading Bibliography or Works Cited or References. Check with your course convenor the preferred heading.
  • In written assignments it is customary to list only the sources that are cited in-text but if you are unsure please confirm with your course convenor.
  • A bibliography list entry ends with a period or full stop even if the last element is a URL.
  • Sorting: Entries are arranged alphabetically by lead author's last name. For multiple works by the same author or group of authors, list them all consecutively, sorted alphabetically by title of article/chapter disregarding any leading A, An or The.
Citation elements
  • Author
    • Only the lead author's name is inverted, i.e. the last name first, followed by a comma, a space, then the first name and any middle initials. Additional authors' names are in natural order.
    • Use authors' names as they appear in the source, including middle initials if provided. Exceptions:
      • If an author's name has initials but also appear as full names in other references, use full names throughout.
      • For different authors with similar last names and initials, do provide full names.
  • Titles: Some works are contained within a larger work (e.g. an article within a journal or a chapter within an edited book) - enclose the smaller work's title in double quotation marks, and italicise the larger work's title.
  • Editions other than first: Include the edition number (not superscripted) or description after the title, with an intervening comma.
    • In the notes:
    1. Andrew Hugill, The Digital Musician, 3rd ed., ...
    • In the bibliography:

      Hugill Andrew. The Digital Musician, 3rd ed.  New York: ...

  • Year: Refers primarily to year of publication. Alternative dates, where applicable, are shown in the format (e.g. Accessed date).
  • City: Include the abbreviated name of the state (if in the USA) or country if the city may be confused with another city of the same name.
  • Notice that citation elements in a bibliography list entries are mostly separated by periods/full stops, and by commas in the notes entries.
Page numbers
  • Include page numbers to lead readers to the cited information in the source, whether you paraphrased or directly quoted in-text.
  • View the full-text PDF of journal articles to see page numbers as they would appear in the journal.
  • Shorter webpages typically have no page numbers in which case you can omit this element.
  • For longer electronic works with no page numbers, e.g. some ebooks, it would be appropriate but not required to cite chapter number, section heading or similar locators for the reader's convenience.
  • A source cited as a whole work (e.g. a reference to a novel as a whole) does not require citation of specific pages.
  • For page ranges above 101, abbreviate the higher page number to the changed digits only, e.g. 519-21,  not 519-521.
URLs and DOIs
  • Use URLs based on the DOI if provided in the source, e.g. https://doi.org/10.1057/978-1-137-48302-7
  • If the DOI is given in this format: doi:10.1057/978-1-137-48302-7, drop "doi:" and append the numbers to "https:doi.org/" as shown above.
  • If the source has no DOI, provide a URL that leads your reader either directly to the cited item or to some information about it. Note:
    • Unless approved by your course convenor, do not use a URL that contains libraryproxy.griffith.edu.au within it as only those with Griffith logins can access the material.
    • Some journal articles are open access and freely available on the web, in which case it will have a direct URL you can use, or you can copy/paste the URL from the browser's address bar.
  • If no DOI or stable URL is provided, state the name of the database where you found the source.
  • Word processors usually underline and turn a URL text blue to indicate an active hyperlink. You can deactivate URLs in Word, but check with and follow your teacher's preferences on whether hyperlinks should be active or not.
