Q. In a list of bulleted points where some are complete sentences and some are not, do you put a period at the end of a sentence, but not the list, or periods after all bulleted points, or none at all?
A. I’m afraid you won’t like my answer: This situation is not covered in CMOS because in a list of bulleted points all the items should be styled with the same syntax, either sentences or sentence fragments.
[Editor’s update: CMOS now concedes, under paragraph 6.141, that each item in such a list, if it must be presented as is, should end in a period.]
