Part 2 - Libraries
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.
