Use a numbered list to display complete sentences or paragraphs in a series (e.g., itemized conclusions, steps in a procedure).
Use a lettered list or bulleted list rather than a numbered list if the items are phrases.
To create a numbered list, use the numbered list function of your word-processing program. This will automatically indent the list as well. Select the option for an Arabic numeral followed by a period but not enclosed in or followed by parentheses.

This guidance is the same as in the 6th edition.
