Revise laws related to state aid to public libraries

This bill amends Montana state law to require public libraries receiving state aid to provide matching funds equal to the grant amount. The matching funds must come from local or tribal government sources, not from other state or federal money. Libraries must submit certification from a responsible official confirming they have secured the required matching funds before receiving state grants. The changes take effect on July 1, 2025, and apply to the distribution of per capita and per square mile funding to public libraries and library districts.
