All money collected for the law library in each county, must be deposited with the treasurer of the county, who must keep the same separate and apart in a trust fund or trust account, to be disbursed by the board of law library trustees. Money may be disbursed only as in this chapter provided, and only for the purposes herein authorized.
Whenever a law library and a board of trustees to govern the same, is in existence under the provisions of any law, other than the law superseded by this chapter, in any county, or city and county, in this State, money so collected shall be paid into the hands of those, and in the manner, provided by such law.
