From Librarian in Black:

A call to action for librarians about the disturbing side effects to library users of the Amazon Kindle format eBook lending in Overdrive, including the threat to intellectual freedom, lost user privacy, and targeted ads pushed at our library users.


While libraries know who currently has a book checked out, most, if not all, delete the history of the book being checked out. The part of the PATRIOT Act that could force them to keep this information was removed, mainly due to the ALA fighting against it and refusing to cooperate.

Libraries and have two very different missions in life. We’ve seen libraries fight to keep your privacy over and over while monetizes every bit of information about you for their own profit. If you didn’t realize that, you haven’t been paying attention.
