Don't purchase hornbooks because the cost can be prohibitive. The law school has a number of hornbooks at the circulation desk in the library as well as older editions throughout the library. A good place to start is the Concise Hornbook series but you can also find other hornbooks for a specific topic using the library catalog. Search the library catalog for your subject such as "property law" and "hornbook. Review the results for items with the location "hornbook reserve" or ask the circulation librarian for recommendations. The most recent copy of these materials will be found in reserve with additional copies located in the First Floor Study Materials section--the bookcase closest to the library Reference Desk.
Hornbooks can help when you create course outlines. When you're outlining, if you don't understand the concepts from the casebook and class notes, read the appropriate section in the hornbook, and see if you then understand enough to outline. The hornbooks discuss cases, so you probably will see an explanation of many of the cases in your case book. The hornbook might just discuss the cases in a way that you understand.
The Library also has commercial outlines and other study aids available for checkout at the Circulation/Reserve desk as well as older versions in the stacks that you can check out and use at home. Go to the library catalog and select "Series" from the drop-down menu and then enter "Examples and Explanations" or "Nutshell" into the search box to pull up all items in the series. Or ask the librarians at the Circulation or Reference desk for titles to fit your course.

Almost every student uses a commercial outline at one time. Commercial outlines can be very helpful in laying out the black-letter law and giving you rules to memorize if that is what you are looking for. Some outlines are geared towards certain casebooks, so some students find those particularly helpful. The problem with commercial outlines is that some students use them in place of reading and working with the material on their own. These outlines are intended to supplement your work, not replace it.
Outlines Available in the Library:
Black Letter Outlines: Comprehensive outline of a particular topic area. These outlines may contain additional subtopics or information that is NOT covered or will be tested on in your particular class. Each book also includes sample exam questions and answers as well as tables of cases, statutes, court rules and other materials referenced in the outline. Browsing through the Chapter Review Checklist at the end of the semester can also be a way to quiz yourself on the material for that topic as the main points are presented as questions for you to answer.
Many of these can be found either new or used on Amazon or other online retailers.
