eLEX's ULTIMATE Guide is perfect for going back to trial armed and ready. Not only does it have the 28 Evidentiary Objections, but it has the litanies (list of questions) for authenticating just about anything you want to put into evidence. Impeachment and refreshing recollection are in there, too.
DON'T GO TO COURT WITHOUT IT!
