N.Y. Education Law § 250: Duplicate department

§ 250. Duplicate department. The regents shall have charge of the

preparation, publication and distribution, whether by sale, exchange or

gift, of the colonial history, natural history and all other state

publications not otherwise assigned by law. To guard against waste or

destruction of state publications, and to provide for the completion of

sets to be permanently preserved in American and foreign libraries, the

regents shall maintain a duplicate department to which each state

department, bureau, board, commission, authority, division, office or

public benefit corporation shall send after completing its distribution,

any remaining copies which it no longer requires. The above, with any

other publications not needed in the state library, shall be the

duplicate department, and rules for sale, exchange or distribution from

it shall be fixed by the regents, who shall use all receipts from such

exchanges or sales for the expenses of and for increasing the duplicate

department or depository of the state library.
