§ 271. Apportionment of state aid to Indian libraries. Any Indian library chartered by the regents or in the absence of such library any tribal government contracting for service from a chartered and registered library or approved library system, shall be entitled to receive state aid during each calendar year consisting of the following amounts:

1. Eighteen thousand dollars, and
