Sonoe,
  Have you considered using a MARC 21 Bibliographic 045 Time Period of Content field?  This field can be a single year/time, multiple single dates or a range, as needed.  This would allow you to have a indexable field with the date of situation.  In the cataloging records for the individual sheets of the HQ Twelfth Army Group situation maps, there an 045 reflecting the exact day of the map, such as in the April 16, 1945 example (https://catalog.loc.gov/vwebv/search?searchCode=STNO&searchArg=2004631937&searchType=1&recCount=10).  Click on the "MARC Tags" tab and you will see an example of our 045.

  Hope this is helpful.

Subject: Date of publication and date of situations

Hi everyone,

Forgive me if this question has already been asked and answered recently.

I have a map with a publication date of 1947.  The date of situation is 1937 (original date 1865 with corrections in 1921 and 1937), however.  I have a 264_1 for the 1947 date.  I plan to put the 1937 in the call number as the date of situation and in a note, but is there also a 264 indicator category that would apply to this date?  None seem to fit exactly.  Thank you for your time and help.
