I’m pleased to announce the 2026 edition (17th edition) of my Internet Law casebook, Internet Law: Cases & Materials. The book is available in multiple formats: a PDF for $10, a Kindle ebook for $10, a softcover version for $20, and a hardcover version for $28. [All printed versions come with a free PDF on request.] For my thoughts about self-publishing an ebook casebook, see this article.

If you’re an academic and would like a free evaluation PDF, email me. I can also share my course slide deck (over 400 slides). You might also check out (1) my Internet Law course page, which includes 29 years of syllabi, old exams, and sample answers, (2) my article on “Teaching Cyberlaw,” (3) my blog post on teaching Internet Law as an online-only course, and (4) my Canvas modules for my Fall 2021 online-only course (I can email you my most current modules on request).

Last year, I made multiple big changes to the casebook. In contrast, this year, I only made one big change: I added the Cox v. Sony opinion and deleted Grokster and the copyright liability excerpt from the Frontier case. Due to the Cox opinion, I rewrote a lot of the copyright chapter.

Other changes of note: I added a new “Short Primer on Tracking Technologies” (an excerpt from Doe v. Adventist Health System/West). I added new notes about trespass to chattels and the Coase Theorem, the SAD Scheme, the Social Media Addiction cases, and more. I also rewrote the section about geolocation technologies.

On top of all of that, as usual, I made hundreds of edits throughout the book.

Over the years, I’ve posted a number of book excerpts, including:

• The entire chapter on online contracts. The 2025 version is available. The chapter would be a helpful supplement to courses wishing to cover online contract formation.
• Primer on CCPA/CPRA (partially deprecated)
• Primer on FOSTA
• Primer on the Copyright Claims Board (CCB) (now deleted)
• Primer on Section 230
• Excerpt on right to be forgotten
• Excerpt on CFAA/Nosal/Power Ventures (now deleted)
• Excerpt on transborder content enforcement
• Excerpt on Brazil’s Marco Civil (now deleted)
• Excerpt on notes about UMG v. Shelter Capital

(Some of these excerpts are now outdated, but every year I update everything that’s still in the book).

As always, I invite your comments and questions.
