One copy of the published book may be kept on file with the ordinance books and constitute an ordinance book. A loose-leaf code or compilation of ordinances published pursuant to this section may be kept current by the periodic preparation of loose-leaf supplements. Whenever any ordinance expresses the intent of the governing body that it may be made a part of such loose-leaf code and the ordinance is thereafter included in a supplement to such code, such inclusion shall have the same force and effect as if the ordinance had been included in the original code at the time of its adoption by the governing body. The governing body shall make provision for furnishing insertions in loose-leaf compilations or codes to municipal personnel, purchasers and others having copies of the compilation or code.
