Type A - items as independent full sentences
The introductory sentence terminates in a colon that introduces a vertical list. Each of the items in the list is a complete sentence that stands independently, opening with an uppercase letter and concluding in a full stop.
Type B - items as run-on, incomplete sentences
The introductory sentence terminates in a colon that introduces a vertical list. Each item is required to run on from and complete the introductory sentence. Each therefore opens with a lowercase letter and concludes in a semicolon, except for the final item.
Type C - items as single words or brief phrases (sentence fragments)
In such lists, the introductory sentence terminates in a colon and each item opens with a lowercase letter, with no end punctuation except for the final full point.
Where possible, choose a system and be consistent in its usage throughout a manuscript; however, in a publication with many diverse lists it may be better to allow all three types rather than to impose an artificial uniformity. Do not allow end-punctuation systems in vertical lists inconsistently.
