Local, regional, and school library material. Requires the establishment of model policies and the subsequent establishment of local policies that are consistent with such model policies on the selection, purchase, curation, display, and removal of library material, as that term is defined in the bill, in local, regional, and school libraries in the Commonwealth. The bill requires such policies, among other things, to prohibit the censorship, as such term is defined in the bill, of library material and to establish a process by which certain individuals with a vested interest in the relevant library may request that the library material be reclassified, moved to a different section of the library, or removed from the library. The bill also permits certain individuals to seek certain types of relief in a court of competent jurisdiction for certain harms suffered as the result of violations of such policies.
