How to Write Good: “If placed in a situation where you must quote another author, always write ‘[sic]’ after any word that may be misspelled or looks the least bit questionable in any way. If there are no misspellings or curious words, toss in a few ‘[sic]’s just to break up the flow. By doing this, you will appear to be knowledgeable and ‘on your toes,’ while the one quoted will seem suspect and vaguely discredited.”
