N.Y. Election Law § 15-112: Registers and poll-books; how used

§ 15-112. Registers and poll-books; how used. For any village election

where permanent personal registration records are not used, all copies

of the register in the polling place shall be referred to, if necessary,

to determine the persons entitled to vote; but at any such election,

including a primary election, ballot numbers shall be entered and other

election entries made in only two copies of the register, which shall

include the copy used for taking signatures; provided, however, that if

the election be one for which poll-books are required to be provided,

ballot numbers shall be entered and other entries made in the two

poll-books instead of the registers. The signatures of voters taken at

the election or at a primary election shall be made or identification

numbers entered, in one of the copies of the register having, when the

election opens, an unused signature column, if there be any such copy,

and otherwise in one of the poll-books, to be known as the signature

poll-book.
