Citation, Documentation of Sources

Q. I’m writing an essay based upon an early explorer’s daily journal and quote extensively from it—do I need to cite it every single time, or is there a way to just cite it once at the beginning and it will be understood that subsequent quotes are from the same source?

Q. Can ibid. be used for parenthetical citations? If so, what is the precise format (e.g., “ibid. 32” or “ibid, p. 32”)? If not, how can one simplify the citation when it appears multiple times in the same paragraph?

Q. I have read in your style guide that it is incorrect to have more than one footnote number attached to a piece of text (e.g., piece of text2, 3, 4) so that footnotes 2, 3, and 4 all contain one citation each. Instead should all three citations be included under one footnote number, and that footnote number be attached to the piece of text?

Q. My question concerns line spacing in footnotes and endnotes in student papers. The CMS is clear that manuscripts submitted for publication should be double-spaced throughout to allow for copyediting, but I can’t see any specific instructions about how to space notes in papers submitted for coursework. Searching has revealed some academic quick guides (based on Chicago) that say to “single-space footnotes and bibliographies, leaving a blank line between entries,” which is the format that I believe to be correct. Is it?

Q. Apologies if this is answered somewhere in the Manual; I don’t see it in the section under Place of Publication. My question: when the place of publication no longer exists, because the city has been renamed or has been absorbed into a larger municipality, how should we cite the place of publication? (Similarly, for books that indicate an alternate English version of the city name, should we use the city name as given, or the more modern/contemporary spelling—e.g., Peking vs. Beijing, Canton vs. Guangzhou, Bombay vs. Mumbai)?

Q. What is the correct way to write an endnote where the author has used a quote from a letter that appears in a volume of letters by someone else, and it appears as one of the book’s appendixes? The book is Delius: A Life in Letters, 1862–1908. The editor is Lionel Carley. The letter quoted by the author of the essay I’m editing is from Jelka Delius, Frederick’s wife. I’ve looked in chapter 14 of CMOS, but can’t find anything that quite matches this. The author has put this:

“Jelka Delius: Memories of Frederick Delius,” appendix 7 in Lionel Carley, ed., Delius: A Life in Letters, 1862–1908, vol. 1 (London: Scolar Press, 1983), 408–15.

Is this correct? Should it be

Jelka Delius, “Memories of Frederick Delius,” in . . . ?

I hope I don’t get scolded for submitting a silly query.

Q. An author wrote the following sentence: “Indeed, there has been extraordinary growth in the field, with the number of publications discussing epigenetics growing from approximately 100 in 1992 to well over 18,000 in the last year.” The citation is to the Google Scholar website. We were unsure what to do with this. Citing the website itself seemed odd, but he did get his information there. How would you handle this?

Q. Hi—A question about CMOS citations with two examples:

(1) Leigh Wood, “University Learners of Mathematics,” in Research in Mathematics Education in Australasia 2004–2007 (Rotterdam: Sense, 2008), 73–98.

(2) Leigh Wood and Ian Solomonides, “Different Disciplines, Different Transitions,” Mathematics Education Research Journal 20, no. 2 (2008): 117–34.

Why does (1), a book chapter, use a comma before the page numbers, whereas (2), a journal article, use a colon? Is it just for historical reasons? It seems a little idiosyncratic for no apparent reason.

Q. How would you cite Aquinas’s Summa Theologica, Question 65, Article 4? Thank you.

Q. We publish books in the water and mining industries. Authors list many references, and we’re finding that in-text citations are becoming more and more excessive. For example, one simple sentence lists seven sources, which seems unreasonable. One chapter is 158 pages long, of which 49 pages are references. Do publishers set some kind of limits on the quantity of citations? Of course it is necessary to avoid plagiarism, but 49 pages of citations seems to be too much! How would you suggest we address this with our authors?
