Hey, guys and gals! (OK, I'm being hopeful here

)
I've pretty much converted all my research tools to one. Google! Fast, simple, and almost always has an answer. If you get close, it even asks if another word in its database is what you're looking for. Sometimes you have to try several spellings, and also you have to be aware that internet users, as a class, are pretty poor spellers, but once you figure out how far to trust the links, it's a wonderful resource.
For instance, Googling for - Gimmik elevator - found no references and a "Did you mean Gimmick elevator?" question. Clicking on that link brought up 23 occurrences. (Don't ya just love doctors' guesses?)
Google had never heard of a tympanotomy weapon though...
Have you tried a military handbook?
