Definition

 
ALL

Dates of production, publication, distribution, manufacture, or copyright, as specified by the code in DtSt. Dates represents two MARC 21 fixed-field elements: Date 1 and Date 2. Each date has four positions usually coded with digits, and they are separated by a comma in OCLC online displays.

Guidelines

 
 

Choose the code for DtSt concurrently with choosing dates in Date 1 and Date 2. For most records you derive date information from field 260 subfield ǂc, field 264 subfield ǂc, field 362, and 5xx notes. For archival collections and manuscript materials you may also derive date information from field 245 subfields ǂf and ǂg. See DtSt for more information.

Serial publications

Use Date 1 and Date 2 for the beginning and ending dates of a serial based on the chronological designations or issue dates appearing on the first and last issues. If the first and last issues are available but lack chronological designations or issue dates, base Date 1 and Date 2 on the dates of publication of the first and last issues in field 260 or field 264.

First and last issues unavailable. If the first issue of a serial is unavailable, do not use the date given in the "Description based on" note. Instead, enter Date 1 with the closest known year, decade, or century and use the letter u for unknown digits.

If the last issue of a serial is unavailable, do not use the date given in the "Latest issue consulted" note. Instead, enter Date 2 with the closest known year, decade, or century and use the letter u for unknown digits if the serial has ceased publication. If the serial is still being published, enter 9999 in Date 2. If the publication status of the serial is unknown, enter uuuu in Date 2.

  • Use u for digits missing in probable dates [Pre-RDA]
  • Enter the date to the closest decade or century, substituting a lowercase u for each missing digit [Pre-RDA]
  • Use uu for the final two characters of Date 2 if the day is unknown for an event known to have occurred on a specific day, such as an original broadcast date. Leave the final two characters of Date 2 blank if there is no day of month given on the item and no day can be inferred. Use the form yyyy,mmdd. [Pre-RDA]
  • Use u for [date of publication not identified] for pre-RDA hybrid and RDA cataloging
