MARC Field 670 in the authority format contains a citation for a consulted source in which information is found related in some manner to the entity represented by the authority record or related entities. It may also include the information found in the source.

ǂu Uniform Resource Identifier  (R)

Policy and formulation

  • The first 670 is the resource you're cataloging that prompted the creation of the NAR (unless the name doesn't appear on the source; see MARC 675 Source Data Not Found).
  • In general, only cite sources that give added information, and limit information to support of NAR data elements. Do not cite multiple sources with redundant information.
  • When citing reference sources, always give the name as it appears on the source; other information can and usually should be summarized and translated.
  • Include a colon before ǂb if citing a specific location, such as "colophon" or a page number. Otherwise, do not precede ǂb with punctuation. Generally, there's no need to cite a specific location if it's not necessary for a person to find the information you're citing, such as a name alphabetically found in an alphabetical resource.
    • If you are citing a multi-volume resource, include the volume number in subfield ǂb, preceding the page number
  • Data elements in the 37X fields must be justified, but they can be inferred. For example, a place name can be inferred from the location of an institution. Gender can be inferred from traditionally male or female names. If the name is gender neutral, or the person's gender doesn't match traditional use, make sure something in the 670 provides an indication of gender. For example (emphasis added): Wikipedia viewed 23 Jan. 2015 ǂb (Michael Learned (born April 9, 1939) is an American actress, best known for her role as Olivia Walton in the long-running CBS drama series, The Waltons)


Electronic resources

  • In general, avoid the use of URLs unless it is necessary to identify the resource and it is a permalink or persistent URL (LC guidelines)
  • Prefer the wording viewed plus the date to indicate that an electronic (born-digital) resource is being cited
    • Always indicate if you are citing a digital surrogate (a digitized print item)
  • Formulate the citation in such a way as to provide the most direct route to the resource
  • Generally, no need to give a location within the source when it's electronic, since it's easily findable anyway, but you'd want to if (for example) the person's name was found in someone else's DNB entry. Just go right into putting the information in parentheses; use a semi-colon to separate chunks of info, e.g. separate the Wikipedia heading from the relevant article info with a semicolon.
  • When citing a library or museum catalog, record the access point as the first element of the ǂb within parentheses, preceded by "heading:" or "authorized access point:"
  • Even when giving a URL, you are required to include information in the NAR 670 to justify data elements.
  • Specific resources
    • VIAF: cite the acronym of the library whose authority record you've chosen, as given in field 003, along with any alternate spellings or other information, such as the occupation and gender if unclear, in the 670. Give original language for controlled vocabulary in authority records, for example, Beruf(e) in Deutsche National Bibliothek records.
      • Some of the more common VIAF library acronyms: DNB (German National Library), BNF (National Library of France), SELIBR (National Library of Sweden), BNE (National Library of Spain), ULAN (Union List of Artist Names), NUKAT (Warsaw University Library)
      • If the VIAF record contains no unique information, you can simply cite it in field 024.
    • Wikipedia: if there is a good-quality article available, prefer that over other sources with the same information, whether primary or secondary (the Wikipedia article is assumed to have aggregated and cited this information already).

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.). Use the person's name if "author" etc. isn't appropriate.
  • Always include the date of correspondence.
