Hi Kathy, I found this one on
www.ebay.com titled "Vocations" by Noel Tyl....it might be the older one, not sure...check it out.
No book in the greater USA has one.....I looked in
www.addall.com/used which lists every bookstore in US.
If I was in your position I would use the SEARCH function Tyl site, in the section re MIDHEAVEN EXTENSION PROCESS.
For eg if you were looking up how to do thread strings for a particular actor, search other actors you know in the MHEP SECTION
and you can easily see how to do them.
I always saved all of Tyl's MHEPs....had 9 binders full of them....threw them all out, cuz knew they are there in the Vocations section of Tyl.
I FOUND ONE....go to
WWW.AMERICANFEDERATIONOFASTROLOGERS.COM ......located in PHOENIX ARIZONA.....
PRICE FOR NEW ONE IS $21.99......if address above doesn't open....google AMERICAN FEDERATION OF ASTROLOGERS/PHOENIX
No idea how many copies they have.......email or phone them.
