Sorry James Jackson but there was an Elders Manual in hardcover book form back in the 70's. It was not as comprehensive as the current version but it was a full size hardcover publication. When I went throught Bethel Entrants School in 1974 it was part of our study curriculum.
Maybe in Bethel and some other areas you had a hardback Elders Procedure Book, but when I was appointed in 1989, the CO handed 3 booklets on directions for the Elders, each had a different copyright date, every Elder on the Body had the same booklets. 2 years later, I moved to another state and The Elders there had the same 3 booklets. Just my experience.
