“NISO [National Information Standards Organization] has published a set of consensus principles for the library, content-provider and software-provider communities to address privacy issues related to the use of library and library-related systems. This set of principles developed over the past 8 months focus on balancing the expectations library users have regarding their intellectual freedoms and their privacy with the operational needs of systems providers. The NISO Privacy Principles set forth a core set of guidelines by which libraries, systems providers and publishers can foster respect for patron privacy throughout their operations. The Principles outline at a high level basic concepts and areas which need to be addressed to support a greater understanding for and respect of privacy-related concerns in systems development, deployment, and user interactions. The twelve principles covered in the document address the following topics: Shared Privacy Responsibilities; Transparency and Facilitating Privacy Awareness; Security; Data Collection and Use; Anonymization; Options and Informed Consent; Sharing Data with Others; Notification of Privacy Policies and Practices; Supporting Anonymous Use; Access to One’s Own User Data; Continuous Improvement and Accountability.”
