Okla. Stat. tit. 65, § 65-3-102: Department as official library of the state

The Department shall constitute the official library of the

State of Oklahoma. The Department shall have custody of all books,

documents, facsimiles, films, maps, manuscripts, pamphlets, papers,

charts, archives, periodicals, records, and any other materials or

objects now in its possession or that may be acquired. No

department or institution of state government, except institutions

of higher learning, museums and the Oklahoma Historical Society,

shall establish a library without prior approval of and except in

cooperation with the Department; provided that this provision is not

to prevent a state agency from having the minimal necessary and

reports or technical publications required to conduct its daily

operations.
