If you do brief, you really want to focus on the issue, holding, and the key facts pertinent to the court's analysis. Also be mindful of hypos that your professor explains in class. What you want to do is set aside time each week to outline, which will help you understand the material. As for book briefing, you can do the multi-color highlighting method, or you can note in the margins of your book the issue, plaintiff's arguments, defendant's arguments, holding, and analysis. I am not sure which edition you are using but I found this searching on Amazon: https://www.amazon.com/Casenotes-Legal-Briefs-Procedure-Casenote/dp/1454805161.
