California's Reader Privacy Act was passed into law in 2011. The law prohibits a commercial provider of a book service, as defined, from disclosing, or being compelled to disclose, any personal information relating to a user of the book service, subject to certain exceptions. The bill would require a provider to disclose personal information of a user only if a court order has been issued, as specified, and certain other conditions have been satisfied. The bill would impose civil penalties on a provider of a book service for knowingly disclosing a user's personal information to a government entity in violation of these provisions. This law is applicable to electronic books in addition to print books.
