I found a geeky 692 page pdf'ed book on the web today.
The title is: HANDBOOK OF PIEZOELECTRIC CRYSTALS FOR RADIO EQUIPMENT DESIGNERS
This Report Supersedes WADC TR 54-248, Dated December 1954
John P. Buchanan
Philco Corporation
OCTOBER 1956
It was originally published in 1956 by Philco Corporation for the Wright Air Development Center. It is 48 Megabytes. I originally found it at an Argentinian website but was unable to grab the url. Become a crystal geek yourself.
