5 Association of Research Libraries Research Library Issues 297 — 2019 privacy as a value, something that will most certainly impact the research and learning community. Ultimately each research library must develop and implement privacy policies and practices within its own institution. Research libraries partner, or may lead, in institutional policy development—usually requiring the creation of a clear and shared understanding of digital and physical privacy decision implications among key stakeholders, including boards, staff, and users. On a day-to-day basis staff need the knowledge of privacy practices in order to assist users, and as needed, evaluate, explain, and act on, privacy events. Privacy practice requires policy compliance in any physical and digital interaction—and with that the institutional capacity to assess and address compliance. Bill Marden, director of privacy and compliance, and Greg Cram, associate director of copyright and information policy, both at The New York Public Library, share important distinctions between privacy and confidentiality, and how New York City public libraries and national endeavors are assisting with privacy policy and practice. We hope you find useful knowledge on privacy in this issue, and we thank the authors for sharing their expertise with you. Mary Lee Kennedy Endnote 1.
