The 13th edition of Wright, Oakley, and Bassett's Cases and Materials on Federal Courts retains the style and structure of the 12th edition, with its distinctive emphasis on cases and annotated footnotes rather than lengthy comments and questions by the editors. The new edition is completely up-to-the-minute, incorporating the changes from the recently-enacted Jurisdiction and Venue Clarification Act of 2011. It includes six new principal cases and fully revised annotations, and omits eleven outdated or less effective case decisions.
