Chicago\u00a0footnote referencing has special rules for repeat citations. If you cite a source more than once, for example, you can use a shortened citation format. But what if you cite one source many times? Or have several frequently cited sources? Let's take a look.\r\nCiting One Source Repeatedly\r\nIf you need to cite one source many times (e.g. if you\u2019re writing a commentary on a particular book or poem), you can give repeat citations in brackets rather than using a footnote every time. You still need to cite the source in full the first time, including the edition you're using (unless it's a first edition). But when you do this, you should add a note saying:\r\n\r\n\tSubsequent citations of the source will be 'text references'.\r\n\tWhat the text citations will reference (e.g. page or line numbers).\r\n\r\nUsually, this note will come after the main citation and say something like 'Text references are to page numbers of this edition'. For instance:\r\n1. Gary Jones, Repeat Citations, 2nd (London: Proofed Publications, 2020), 45. Text references are to page numbers of this edition.\r\nAfter this, you can give pinpoint references in brackets in the main text. Here, for instance, we've citing page 34 of the source in the footnote above:\r\nHe confirms that \u2018it\u2019s important to understand repeat citations\u2019 (34).\r\nThis works fine if you\u2019re only citing one source repeatedly. But what about if you\u2019re referring to lots of different sources? Read on to find out.\r\nAbbreviating Frequently Cited Sources\r\nIf you\u2019re citing a few different sources repeatedly, you need to let the reader know which one you\u2019re referring to each time. And to do this in Chicago referencing, you can use abbreviated source titles.\r\nThis works by giving the shortened title at the end of the first footnote citation for each source you plan to cite repeatedly. After that, you can either give the abbreviated version in the main text or in a footnote.\r\nIf you are using in-text citations, make sure to note this in the first footnote:\r\n3. Anthony Palmer, The Joys of Referencing, 3rd edn. (London: Proofed Publications, 2020), 38 (hereafter cited in text as TJR).\r\nSubsequent citations would then require giving the abbreviation and a pinpoint citation in brackets:\r\nPalmer seems genuinely excited by citations (TJR, 42).\r\nFor repeat footnote citations, meanwhile, you just need to give the abbreviated title in the first footnote:\r\n4. Bobby Greene, Guidelines for Referencing in Chicago Style (London: Proofed Publications, 2018), 60 (hereafter cited as Chic. Guidelines).\r\nAfter that, you can use this abbreviated title, plus a pinpoint citation, each time you cite the source. For example:\r\n8. Chic. Guidelines, 65.\r\nIf you have ten or more frequently cited sources, moreover, you should add their abbreviated titles to a list of abbreviations at the start of your document (typically titled \u2018Abbreviations\u2019). This will help your reader keep track of the various abbreviations used in your writing.\r\nFinally, if you want someone to double check the referencing in a document, or any other aspect of your writing, our team of expert academic proofreaders is always at the ready.
