Citation, Documentation of Sources

Q. I believe there is an errant dash in the example citation at CMOS 14.119, following “1992”: Armstrong, Tenisha, ed. To Save the Soul of America, January 1961–August 1962. Vol. 7 of The Papers of Martin Luther King, Jr., edited by Clayborne Carson. Berkeley: University of California Press, 1992–. Huge fan of CMOS!!

A. Though it does look kind of odd, that 1992 followed by an en dash and a period is Chicago style for citing the date of an unfinished project; see CMOS 6.79. And according to the project’s publisher (as of March 5, 2024), volume 7 is only the latest in what is projected to be a fourteen-volume collection of King’s papers; see “King Papers Publications” at the Martin Luther King, Jr. Research and Education Institute (via Stanford University).

Note that Chicago style doesn’t require a comma before “Jr.,” but we retain one in the project title and the name of the institute to reflect the publisher’s usage. Note also that the citation in the question can be reordered to put the collection before the individual volume, in which case only the year for the volume would be cited (as in the first example at CMOS 14.119).
