Okla. Stat. tit. 53, § 53-1.21: Entry fees at museums and historical sites

A. The Oklahoma Historical Society is authorized to charge at

its discretion an entry fee at all of its museums and historical

sites.

B. The Board of Directors of the Oklahoma Historical Society

shall establish an entry fee schedule to charge the public for

admission to the participating sites. The entry fee schedule shall

include special rates for families, school groups and any other

group or category of persons the Board designates. Residents and

nonresidents of this state seventeen (17) years of age and younger

shall not be charged an entry fee at least one (1) day per week.

The day of the week shall be designated by the Board.

C. The Oklahoma Historical Society shall separately account for

and report the revenue which is generated from the collection of the

entry fee for the participating sites. After the collected fees are

deposited in the Oklahoma Historical Society Revolving Fund, the

Oklahoma Historical Society shall separately track the fee revenue

generated from each site to ensure that all revenue accruing to the

credit of each site is budgeted and expended for that site. The

revenue shall be used at each site to enhance, improve, market and

pay for expenses associated with the site including, but not limited

to, site personnel, utilities, conservation supplies, site promotion

and marketing, equipment, professional services and capital

improvements.

D. The Board of Directors of the Oklahoma Historical Society

shall evaluate the overall effectiveness of charging an entry fee at

the participating sites, including the impact on educational

outreach, public opinion and operational efficiency.

E. The amount of money appropriated to the Oklahoma Historical

Society shall not be reduced to offset the amount of revenue

generated and collected through the charging of entry fees.
