CNet reports on a letter from (pdf) the ACLU, Electronic Frontier Foundation and Samuelson Law Technology & Public Policy Clinic at UC Berkeley Law to Google concerning privacy in its Book Search service. The groups said:
Under its current design, Google Book Search keeps track of what books readers search for and browse, what books they read, and even what they “write” down in the margins. Given the long and troubling history of government and third party efforts to compel libraries and booksellers to turn over records about readers, it is essential that Google Books incorporate strong privacy protections in both the architecture and policies of Google Book Search. Without these, Google Books could become a one-stop shop for government and civil litigant fishing expeditions into the private lives of Americans.
EFF is urging the public to take action and write to Google to demand privacy for their online reading data.
