Many agencies have brochures, handbooks, manuals, or other publications which contain their rules. These rule texts are not official. The official rule text is the text as published in the Register and included in the Code [75:250.7 and 75:256(A)(1)]. Agencies are urged to use the two-person proofreading method to check agency publications against the official Code or Register text.
