The Tenth Edition features updated and expanded coverage of electronic sources, both subscription-based (including Bloomberg Law, Westlaw, Lexis Advance, Checkpoint, Wolters Kluwer (CCH), Federal Research Library, 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. There are updated problems for students to solve throughout the text. The Tenth Edition has many illustrations that complement its textual discussions.
