A more thorough explanation:

A sequential journal is a record of notarial transactions kept by a notary public. It is usually a bound book that lists the date, time, and type of each official act, the type of instrument acknowledged or verified before the notary, the signature of each person whose signature is notarized, the type of information used to verify the identity of parties whose signatures are notarized, and the fee charged. This journal is required by law in many states and provides a record that may be used as evidence in court.

• A notary public in California keeps a sequential journal of all notarial acts performed, including acknowledgments, jurats, and oaths.
• In New York, a notary public must keep a sequential journal that includes the date, time, and type of notarial act, the type of document, the name and address of the signer, and the fee charged.

These examples illustrate how a sequential journal is used to keep a record of notarial transactions and ensure compliance with state laws and regulations.
