1a. New MARC Authority Fields: 046, 370

New MARC Authority fields potentially applicable to series: 046 -- 370 -- 377 -- 380 -- 381

Notes, Quotes, & Guidelines from STTF MARC21 in NACO RDA Series Authority Records

046 Special Coded Date (NR)

Sources: LC MARC 21 format for 046 - Special coded dates and DCM Z1


k Beginning or Single Date created (NR) For a work, earliest date (normally the year) associated with a work; that date may be the date the work was created or first published or released.

‡l Ending Date Created (NR) Ending date of the date range for which the beginning date is recorded in ‡k

Extended Date Time Format (EDTF)

The date and time are recorded according to Extended Date Time Format (EDTF) in the pattern using 4 digits for the year, 2 for the month, and 2 for the day, each element separated by a hyphen:

  • year = yyyy
  • year and month = yyyy-mm
  • year, month, and day = yyyy-mm-dd
  • Use subfield ‡2 edtf to indicate the date schema

PCC Practice for justifying 046

  • 670 field
  • ‡u Uniform Resource Identifier (R)
  • ‡v Source of Information (R) 

Trainer Notes:

  • use of delimiter v is optional if the same information/source is already cited in the 670
  • use delimiter v if the information/source is not cited in a 670
  • use of delimiter u is optional, and should always be preceded by delimiter v.
  • use of delimiter 2 (​‡2 edtf) is required

370 Associated Place (R)

  • See RDA 6.5
  • No indicators
  • Subfields

‡g  Place of origin of work (R) – country or other territorial designation from which a work originated
‡s  Start period (NR)
‡t   End period (NR)

Trainer notes: "For a work or expression: The country or other territorial jurisdiction from which a work or expression originated.

‡g is used to record the jurisdictional information.  ‡s and ‡t can be used to indicate start and end dates.

Of course, this is usually recorded in the 643 field too."

370 justification: same as 046: 670, ‡u, ‡v, ‡2

The STTF training slides pre-date the decision to use the NAF form punctuation. Catalogers should now use the NAF punctuation as found, e.g Chicago (Ill.) NOT Chicago, Ill.

If the source is the naf, ‡2 is not necessary. Some libraries add it routinely. Definitely use ‡2 if the source is lcsh

Example. Place of origin of the series changes.
