The Used and Rental copies of this book are not guaranteed to include any supplemental materials. Typically, only the book itself is included. This is true even if the title states it includes any access cards, study guides, lab manuals, CDs, etc.
The Eighth Edition features expanded coverage of electronic sources, both subscription-based (such as Westlaw, LexisNexis, Checkpoint, CCH IntelliConnect, and HeinOnline) and those available without charge (particularly those provided by the government). It discusses factors to be considered in deciding between print and online research; chapters discussing primary sources illustrate several online sources for finding these materials. This book devotes considerable space to publicly available IRS documents and legislative history materials. The introductory materials illustrate solving a research problem, and there are problems for students to solve throughout the text. The Eighth Edition expands the number of illustrations that complement its textual discussions.
