The ordinance book, or copies of ordinances as recorded therein, certified by the city auditor, shall be received as evidence without further proof. If the ordinances of a municipality have been printed in book or pamphlet form by authority of the governing body of the municipality, such book or pamphlet shall be received as evidence of the existence of the ordinances therein contained.
