Tennessee Code Title 40. Criminal Procedure § 40-39-216

(a) Public library boards shall have the authority to reasonably restrict the access of any person listed on the sexual offender registry. Such authority may be delegated by the board to a library administrator.

(b) In determining the reasonableness of the restrictions, the board shall consider the following criteria:

(c) Nothing in this section shall prevent the board from imposing a total ban of the offender's access to a public library so long as the criteria in subsection (b) are considered.

(d) The restrictions of this section shall be effective upon the mailing of notice to the address of the offender as listed on the sexual offender registry. The notice shall state with specificity, the time and space restrictions. The board, or if so delegated, the library administrator, shall state in the notice that the criteria in subsection (b) have been considered.

(e) A registered sex offender who enters upon the premises of a public library in contravention of the restrictions five (5) days after mailing of the notice may, at the discretion of the library administrator, be prosecuted for criminal trespass pursuant to § 39-14-405.
