Privay law prof Daniel Solove has updated versions of some his books out. Over on Concurring Opinions, he writes:
The new edition of my casebook, Information Privacy Law (4th edition) (with Paul M. Schwartz) is hot off the presses. And there’s a new edition of my casebook, Privacy, Information, and Technology (3rd edition) (with Paul M. Schwartz). Copies should be sent out to adopters very soon. If you’re interested in adopting the book and are having any difficulties getting a hold of a copy, please let me know.
You also might be interested in my concise guide to privacy law, also with Paul Schwartz, entitled Privacy Law Fundamentals. This short book was published earlier this year. You can order it on Amazon or via IAPP. It might make for a useful reference tool for students.
