Lists of short items (without main verbs) should be introduced by a full
sentence and have the following features:
- introductory colon
- no initial capitals
- no punctuation (very short items) or comma after each item
- a full stop at the end.
Where each item completes the introductory sentence, you should:
- begin with the introductory colon;
- label each item with the appropriate bullet, number or letter;
- end each item with a semicolon;
- close with a full stop.
If all items are complete statements without a grammatical link to the
introductory sentence, proceed as follows:
a. introduce the list with a colon;
b. label each item with the appropriate bullet, number or letter;
c. start each item with a lowercase letter;
d. end each one with a semicolon;
e. put a full stop at the end.
If any one item consists of several complete sentences, announce the list with a complete sentence and continue as indicated below:
1) Introduce the list with a colon.
2) Label each item with the appropriate bullet, number or letter.
3) Begin each item with a capital letter.
4) End each statement with a full stop. This allows several sentences to be included under a single item without throwing punctuation into confusion.
