Over the years, I've contributed modestly to the literature on legal writing with three articles in the Illinois Bar Journal. Okay, so none of them were peer-reviewed, but I put them on my website anyway:
"First Drafts Made Easy, "IBJ 6/03.
"Five Steps Towards Persuasive Writing," IBJ 6/98.
Articles about legal writing never age--so hop right in! Maybe you'll see a tip that will help. However, if you want to see how an expert has covered legal writing, try "Barger on Legal Writing," a website that's devoted solely to legal writing by a law school professor.
