[Avodah] Subject: Ashkenazi Minhag

Re:  <<Are there any recommended sources on this topic>>, 
the topic being the different starting points of the chazan 
shacharit on yom-tov.

The best sources that verify the different starting points 
are the old machzorim,  the Roedelheim  machzorim of R' Wolf 
Heidenheim especially. The me'iti machzorim (published 
during Heidenheim's lifetime) are obviously the best.  I 
have a me'et machzor (after his death) for Sukkot published 
in 1859 which also starts shacharit with Hagadol. So the 
custom was still alive then.

Sorry, I have never looked for background material on this 
subject so I must limit myself to verifying the existence of 
the custom./
