Citation, Documentation of Sources

Q. I am writing a long research paper, and in almost every page the footnotes take up nearly half the page. Most of my sources have URLs with them; am I allowed to take out all of the URLs in the footnotes if they are included in my bibliography?

Q. Many online journals are switching from continuous pagination of their articles to assigning each article a number. I’m working with a company that wants to incorporate these article numbers in their citations. Where would the article number go in the citation?

Q. I am editing a paper and changing the citations into Chicago style. The sentence in question reads: “In terms of the transition from a sociology of labour, there has been enough uptake to allow for such assessments (see Lier 2007; Castree 2007; Coe and Lier 2011; Rutherford 2010; and Coe 2013 for a more recent review).” How would I cite this in Chicago?

Q. I’m trying to write a footnote for a book that has been revised and enlarged. How do I cite the reviser? This is what the author has currently provided: James Boswell, Life of Johnson, ed. George Birkbeck Hill, revised by L. F. Powell, rev. ed. (Oxford: Clarendon Press, 1934–64), 2:365. I feel that if I include Powell it should be abbreviated somehow—“rev. by” or something. Should I treat him like an editor instead?

Q. I am citing a letter from a volume of documents that was once part of a manuscript collection at an archive. I have a photocopy of the letter, made twenty-five years ago when the volume was at the archive, but the volume has since been stolen. How do I cite the letter?

Q. In my footnotes, I want to cite something as well as explain what it is I have cited, because I do not want to insert the info in the body of my paragraph. How do I do this? Does the citation go first or the explanation?

Q. How do I cite a Google Forms survey that I have conducted for my research paper in Chicago format?

Q. Hello, how do I cite an electronic thesis that I found on the web?

Q. I found a nice comment written in a book by the last owner. Have no idea who that was, but the words are good. How do I cite this?

Q. I am teaching my students CMOS notes and bibliography type for all of their academic papers. When using footnotes on a paper the student did the full bibliographic citation on page 1. Then on page 2 there was a reference to the same source. Is it correct to allow the student to simply use author-date for that subsequent citation? Or is it more correct for the student to repeat the full bibliographic citation?
