*During a special meeting on March 13, 2023, the IAC Board of Directors determined that changes to the Starting Line section of the rules are appropriate.  These have been incorporated into the 2023 Rules as Revision A.  The only differences from the original 2023 book are in paragraphs 9.3 and 9.4 (pages 7 and 8), plus the title sheet that denotes the revision letter so if you have already printed the previous version, you only need to swap out those 3 pages.
