(a) All registration records, when not in the custody of the registrars, shall be and remain in the custody of the department except as otherwise provided.

Anyone desiring to do so may be permitted to make copies or partial copies thereof.
(b) Any registered voter may have that registered voter's telephone number removed from the electronic voter registration files by making the request of that registered voter's local department of elections, either by telephone or in writing.
