OLAC Best Practice for restriction on access to manifestation

Record any restrictions on access to the manifestation or item in MARC field 506. Be as specific as possible about the nature of the restrictions. For tangible resources that are archival in nature, record information about restrictions on access if the information would apply to the public beyond one's local institution; such notes may be recorded in shared cataloging. Limit recording information on restrictions on use that does not apply beyond one's local institution to one's local catalog only. Availability via open access is important to record for online resources.

Apply the option for online resources. OLAC recommends using Standardized Terminology for Access Restriction from the DLF/OCLC Registry of Digital Masters Working Group (STAR).
