✅ We’ve done our best to create a comprehensive and accurate textbook and study guide.

👓 It has been carefully reviewed by numerous editors, faculty and students at universities and colleges across the country, and used by thousands of students here at Duke and elsewhere.

📚 That said, the books together are over 2000 pages, and therefore, there may still be mistakes or typos that have been missed.

🔍 Think you’ve found a mistake? Good eye! Follow the steps below.


  1. Check the most updated version of the errata to make sure we haven’t located it already.
    1. Textbook errata (7th edition)
    2. Study Guide and Solutions Manual errata (7th edition)
    3. other versions
  2. If it looks like an undiscovered error in the 7th edition, let Jim know by email.
  3. I’ll confirm that you have, in fact, found a new error. If so, you’ll get +1 point on the next exam!
    1. Criteria:
      1. No more than +3 points per student/semester.
      2. It must appear in a 7th edition. Older editions are out of print.
      3. The error or typo must obscure understanding of the problem or topic. These could be errors in a structure, wording that is inconsistent or confusing, or information that is incorrect.
      4. Minor errors, like a missing punctuation mark, minor typos, or an issue with artwork that doesn’t affect comprehension, aren’t eligible for bonus points, but are still helpful to report to improve our course materials.
      5. If multiple students report the same new error, I can only award a bonus point for the first one to notify me (determined by timestamp on the email).
  4. Thank you for letting me know!
