The Holt Rinehart edition was 3-hole punched. The original V7
(and its predecessors) were prepared for AT&T standard 4-hole binders, but
distributed in Accopress binders that used only 2 of the 4.

4-hole paper was punched 2" and 3 3/8" from top and bottom of 11" paper.
This reduced the stress concentration that makes the isolated end holes in
3-hole paper vulnerable to tearing out. It was a let-down when AT&T
eventually acceded to a sort of loose-leaf Gresham's law and switched to 3
holes.
