Winning Trial Advocacy Tips continues to be a great source of information for those of us who try cases. This post, called "The Proper Use of Notes," does a fine job explaining how – and how not – to use notes at trial.
An excerpt:
When preparing the notes that you’ll bring to court, instead of writing out a word-for-word script, write down only what you need. Rather than full sentences, use brief phrases or single words. Besides, when you’re in the heat of trial, your eyes won’t easily focus on full sentences like “Mrs. Johnson, would you please tell us how you know the defendant?” All you’ll really need is a quick reminder, like “RELATIONSHIP?” or “KNOWS DEFENDANT?” to prompt the correct question.
