Any circuit judge may, whenever he or she deems it desirable, purchase or direct the clerk of the circuit court for any county in his or her circuit to purchase law books and subscribe for the periodical reports of any of the courts of the several states or territories or of the United States, for any county in his or her circuit, provided the cost of the books and reports, including pocket parts and continuing services, shall not exceed $1,500 for any county in one year, unless the board of supervisors of the county authorizes the expenditure of a larger sum. Whenever the purchase or subscription is made the clerk shall have each volume of books received stamped or branded with the name of the county and take charge of the same for the use of the courts, judges, attorneys and officers thereof. The cost of the volumes shall be paid by the county treasurer upon the presentation to him or her of the accounts therefor, certified to by the clerk of the circuit court and the circuit judge.
