The style and punctuation of enumerations in running text shall conform to the following rules:

1. (1) The items in the tabulated enumeration shall belong to the same class, for example, the enumeration shall have a common theme or thread.
2. (2) An item in the tabulated enumeration shall be responsive, in substance and in form, to the introductory language of the enumeration—the material immediately preceeding the colon.
3. (3) If the sentence of which tabulated enumeration is a part continues beyond the end of the enumeration, the part of the sentence that follows the enumeration shall be appropriate to each item.
4. (4) Material immediately preceeding or following the enumeration may not be indented unless it marks the beginning of a paragraph.
5. (5) If the tabulated material takes the form of a sentence in which the enumeration is an integral part, each item shall begin with a capital letter and end with a period.
6. (6) If the tabulated material takes the form of a simple list following a sentence that is otherwise complete, each item shall begin with a capital letter and end with a period. No ‘‘and’’ or ‘‘or’’ follows the penultimate item.
7. (7) Selection of an appropriate introductory phrase to the tabulated material will normally be sufficient to make the meaning clear.
