For example, the real title is "Cooking vegetables: Beans, carrots and spinach". But on the cover that would be graphically punchier as:
Cooking vegetables:
- Beans
- Carrots
- Spinach
No comma and no "and". I would want the full title - "Cooking vegetables: Beans, carrots and spinach" - on the title page and in everything else that refers to the book, page headings, ISBN title, publicity.
