Policy and formulation

Electronic resources

  • In general, avoid the use of URIs unless 1) it is necessary to identify the resource and/or 2) it is a permalink.
  • Prefer the wording viewed on plus the date to indicate that an electronic resource is being cited
  • Specific resources
    • VIAF: give the permalink to the VIAF cluster or an individual authority record as appropriate

Personal communication

See Contacting people for authority control for guidelines
  • Per the NACO Participants' Manual, the citation can be specific ("Email from author," "Phone call to publisher," etc.) or general ("information from author," "information from publisher," etc.). Either way, include the date of correspondence.
