You will find study aids to be valuable tools for class and especially when preparing for finals. There are more than a dozen different series of study guides available from a number of publishers. Study aids come in many different forms: overviews, outlines, checklists, Q&A's, flow charts and flash cards to name a few.
You can find a study aid for nearly every class offered.
The Law Library has most current editions of Study Aids on Reserve for a 2-hour checkout, as well as many of the older editions in the stacks upstairs for longer checkout.
UPDATE: Items on Reserve will circulate for 24 hours in Fall 2020. All books returned will be quarantined for 3 days.
