Citation, Documentation of Sources
Q. In 14.181 (16th ed.) you only have “No volume number or date only,” but what about no issue number but volume only? What is the correct way of reference? Ecological Economics 82, 23-32 or Ecological Economics 82: 23-32?
A. A colon is more clear. In some cases the numbers in the citation would be confusing with a comma.
Journal Title 18, 23–32.
Journal Title 18, 6, 12.
Journal Title 18:23–32.
Journal Title 18:6, 12.
[Update: CMOS 17 illustrates this scenario. See paragraph 15.48.]
