This document discusses privacy issues related to libraries in the digital age. It provides an overview of privacy laws in the US and how they relate to libraries. While the right to privacy is not explicitly outlined in the Constitution, many court cases have recognized this right. Most states have passed laws to protect library user privacy, though these laws often do not address new digital technologies. The document examines challenges to privacy from entities like the FBI and technologies like digital records, filters and reference services. It concludes with recommendations that libraries update policies to collect minimum data, limit access, inform users of policies and collaborate with vendors on security.
