For lists in running text, use a comma after the second-to-last item:
Lawyers, guns, and money. Lawyers, guns, or money.
Use a bulleted list to make a long list of short items easier to read. However, don't overuse bulleted or numbered lists; too many lists on a page can create visual confusion.
Format a bulleted list as follows:
- The introductory phrase should end with a colon.
- Each list item begins with a capital letter.
- List items should have no punctuation, unless they are complete sentences.
- Indent each bulleted item.
Commas or semicolons at the end of list items is not necessary.
Avoid using bullets if the bulleted items will include multiple complete sentences.
Whenever possible, try not to break bulleted lists or the list items themselves across columns or pates.
