I'm a trained professional. Don't try this at home.

I couldn't remember a little factoid on one of the worlds I'm writing about, so I hunted around until I found a couple good sites on the subject. And by the time I found my answer, I had noticed a few other areas where I had described something inaccurately... okay, a LOT of areas. So finally I just torn through the sites from beginning to end, looking for any other errors that might have snuck into my writing. Came out with a list of corrections a mile high (thankfully, nothing fatal to the overall plot). I'm nothing if not thorough, but sometimes I wish I could just let mistakes be. >_
