wondering where that comma goes, guv'nah? (meme)

this Wikipedia entry is a useful and thorough guide to differences between American and British English. It helped me settle a copy-editing question, and I must therefore promote it.

This is also a good chance to promote The Economist's style guide, particularly the section on Americanisms.

"Gubernatorial is an ugly word that can almost always be avoided."
"Make a deep study or a study in depth, but not an in-depth study."
"Try not to verb nouns of adjective them."

Also, take the style quiz. I got nine out of twelve the first time-- missed a hyphen rule, a plurality rule, and a rule about "last" vs. "latest." Not an awful score, but it doesn't bode well for my future as a copy-editor, growl.
