Dates represents two MARC fields: Date 1 and Date 2. Each date has four digits, separated by a comma.
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 ‡c,
field 261 subfield ‡d for Pre-AACR1 Revised films,
field 262 subfield ‡d for pre-AACR2 sound recordings,
field 362 (Dates of Publication and/or Sequential Designation) and notes (5xx). See DtSt for more information.
BKS, VIS, MIX, MAP, SCO, REC, COM
Date 1 may be system-supplied by automatic transfer from the imprint (
field 260 subfield ‡c).
CNR

field 533 and
