​Evidence: Cases, Materials, and Problems by Rothstein, Crump, and Lawson is the best casebook available for understanding the Federal Rules, using them, and debating about them. It is right up to date, with plenty of cases from the twenty-teens. Organized principally according to the Federal Rules, with significant state variations occasionally noted, the book's copious, very descriptive section and subsection headings will help the professor to assign those parts that are desired. There are problems throughout that challenge students both to apply newly learned concepts and to resolve issues at the cutting edge. Areas that deserve less analytical attention but are nevertheless important for the student to know something about, are succinctly summarized in the book by time-saving informational text, rather than cases. Such text can be assigned and may not even need to be discussed in class.
