§ 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.
