UFFC has some excellent resources on the web which does not require you 
to be a member to use:
http://www.ieee-uffc.org/frequency_control/teaching.asp

If you go for "Doubly Rotated Thickness Mode Plate Vibrators" by Arthur 
Ballato (one of several usual suspects)
http://www.ieee-uffc.org/frequency_control/teaching/pdf/Ballato.pdf

On page 16 you find that both of them get's referenced for the SC-cut, 
but with years being reversed from what has been given in this thread.

Regardless, there it is. Online. For free. Take it and run with it Jim!

Please make liberal use of that UFFC teaching resource.

As I recall the Wikipedia stuff, they prefer free web-references over 
others, but it's not completely ruled out to use sources not available 
on those terms. It just makes it harder to check when they can't read it 
widely.

Cheers,
Magnus
