UC Berkeley Library Code of Conduct

Revised and affirmed by Library Cabinet, July 2023

The UC Berkeley Library strives to provide access to well-maintained collections, information resources, equipment, and associated research services. The Library also seeks to provide a safe and secure environment and facilities suitable for reading, learning, and other activities associated with scholarly teaching and research.

The following code of conduct is intended to ensure a respectful and productive environment for study and research for all users. These policies are applicable to all Library users and are enforceable by all Library staff.

Library use is a privilege. If an individual or group is not adhering to Library policies, individual users may point it out. Concerns, problems, or policy violations may also be reported at a Library service desk to any Library staff member.

Anyone violating these policies can be asked to leave the Library and refused future access. Library users found in violation of this code of conduct may be: asked to present identification to Library staff; subject to a search of backpacks or bags; directed to leave the premises; suspended from access to all Library facilities for a period of time; and reported to the University of California Police Department. Disciplinary or legal action may be taken in accordance with applicable federal, state, city, and campus laws and policies. Depending on the severity of the offense and the pattern of behavior, persons may be banned for extended periods such as one week, one year, or permanently; bans cover all campus Library locations and services.
