But I was under the impression if you only had the birth year or death year you do it as follows:
Abraham Lincoln (b. 1809)
Abraham Lincoln (d. 1865)
A professor of mine stated that you use a question mark: Abraham Lincoln (1809–?)
I have never seen this before, and frankly it looks awful.
I cannot find where this is discussed in the CMS, although I have seen them use both dates in examples. Does anyone know how the CMS recommends handling this situation? I am using the 15th ed.
Any help is greatly appreciated!
