As with most citation systems, Chicago referencing requires you to list all cited sources at the end of your document. However, this differs slightly depending on the system you\u2019re using:\r\n\r\n \tWith the footnote version of Chicago, you need a bibliography.\r\n \tWith the author-date version, you need a reference list.\r\n\r\nThese are similar in practice, but make sure you know which version you need before finalising the list of references in your document. And to help you get this right, we\u2019ve compiled some key information on how to format a bibliography or reference list in Chicago referencing below.\r\nHow to Format a Bibliography (Chicago Footnotes)\r\nWhen using the Chicago footnote system, you will list all cited sources in a bibliography at the end of your document. The main rules for formatting a Chicago bibliography are:\r\n\r\n \tStart it on a new page at the end of your document titled \u2018Bibliography\u2019.\r\n \tInclude all sources cited in footnotes other than personal communications (e.g. unpublished letters and emails).\r\n \tArrange sources alphabetically by the surname of the first listed author. If a source has no named author, use the first main word of the title instead.\r\n \tInvert the first listed author\u2019s name for listing the source alphabetically.\r\n \tAdditional authors names can be listed in the conventional order.\r\n \tUse the conjunction \u2018and\u2019, not the ampersand (&), between the last two author names for works with two or more authors.\r\n \tFor works with ten or more authors, list the first seven followed by \u2018et al.\u2019.\r\n \tWhen citing more than one work by an author, order them alphabetically by title. In addition, while you should give the author's name for the first reference, subsequent entries should use three em dashes in place of the author's name (e.g. \u2014\u2014\u2014. Title of Work. Publication Information).\r\n \tItalicise titles of books, journals, and other standalone publications.\r\n \tUse \u2018quote marks\u2019 for titles of articles and book chapters.\r\n \tFor website and book series titles, don\u2019t use italics or quotation marks.\r\n \tUse title case for all titles, including books, websites, and articles.\r\n \tProvide DOIs instead of URLs for online sources whenever possible.\r\n \tUse a date of access when an online source has no date of publication.\r\n\r\nAs with any reference list, though, the most important factors are:\r\n\r\n \tProviding enough information for your reader to identify each source.\r\n \tUsing a clear and consistent style for all references.\r\n\r\nHow to Format a Reference List (Chicago Author-Date)\r\nThe format for a reference list in Chicago author-date referencing is essentially the same as above. However, there are a few differences:\r\n\r\n \tUse the title \u2018References\u2019 at the top of the page.\r\n \tWhen citing multiple sources by a single author, arrange them by the date of publication (not the title of the source, as described above for the bibliography). As with the notes and bibliography system, use three em dashes for each entry after the first.\r\n \tWhen citing two or more works by the same author from the same year, add a letter after the year of publication for both citations and reference list entries (e.g. 2012a, 2012b, 2012c).\r\n\r\nExcept for these differences, use the format for a bibliography set out above.\r\nChicago Referencing Proofreading\r\nYou can find out more about referencing different source types in Chicago referencing on this blog.
