This title is available in our CasebookPlus format. CasebookPlus provides support beyond your classroom lectures and materials by offering additional digital resources to you and your students. Anchored by faculty-authored formative self-assessments keyed to our most popular casebooks, CasebookPlus allows students to test their understanding of core concepts as they are learning them in class — on their own, outside of the classroom, with no extra work on your part. CasebookPlus combines three important elements:

  • A new print or digital casebook
  • Access to a downloadable eBook with the ability to highlight and add notes
  • 12-month access to a digital Learning Library complete with:
Multiple-choice self-assessment questions, including:
  • Chapter questions keyed to the casebook
  • Black Letter Law questions (available in select subjects)
  • Subject area review questions for end of semester use
Essay and short answer questions with sample answers and expert commentary, in 1L and select upper-level subjects

With CasebookPlus, you can customize your students' learning experience and monitor their performance. The quiz editor allows you to create your own custom quiz set, suppress specific quiz questions or quiz sets, and time-release quiz questions.
