During trainings, I and other instructors often mention that the 1998 consultation handbook has a few errors in it and that some of the practices mentioned there have either been changed or fallen out of favor. Invariably we’re then approached after the class by new practitioners wanting to know if someone has put together a document identifying these points. Though an Errata Sheet was put out late in 1998 describing a few typos etc., I don’t know of anything more detailed. I’ve always been a little embarrassed at that, so I took a copy of the 1998 handbook and used PDF “sticky notes” and highlighting to point out all the important discrepancies that I’m aware of (including those noted in the Errata Sheet). If you know of any additional ones, feel free to contact me and together we might be able to help practitioners out until a revised handbook replaces the 1998 edition.
