Every (i) library board established pursuant to § 42.1-35 or (ii) governing body of any county, city, or town that, pursuant to § 42.1-36, has not established a library board pursuant to § 42.1-35 shall establish an acceptable use policy for the Internet designed to (a) prohibit use by library employees and patrons of the library's computer equipment and communications services for sending, receiving, viewing, or downloading illegal material via the Internet, (b) prevent access by library patrons under the age of 18 to material that is harmful to juveniles, and (c) establish appropriate measures to be taken against persons who violate the policy.
