This field contains 40 character positions (00-39) that provide coded information about an item.
For fuller specifications of this field see the MARC 21 documentation. The following are the codes to enter in the Books format (which is the standard for a manuscript volume or item). If you have a form other than Books, then character positions 18-34 will be different. Please refer to the MARC 21 documentation for other material forms.
The MARC 21 standard for a “full level” record requires certain of these character positions (or bytes) to be filled in. The entry for these may be blank, but it cannot be a fill character ( | ). These positions are shown in bold below
(00-05) Date entered on file (system-supplied)
(06) Type of date
b B.C. date involved (use 046 field)
i inclusive dates for a collection. Use this for a group of distinct items, e.g. letters, that are bound together.
s single known or probable date
m multiple dates. Use this for a work that is executed over a period of time that can be specified. This would include a manuscript that contains annotations or additions made after its first copying.
n date unknown
q questionable date. Use this only for a single date that can be narrowed to within a range of years.
(07-10) Date 1
(11-14) Date 2 (if needed)
The value in (06) and the date(s) in (07-10) and (11-14) are determined by the date in the the $$f subfield of the 245 field. Date 2 is entered only if you have entered “i,” “m,” or “q” in (06). Enter “u” for uncertain digits in dates. Also use “u” as shown below for an undated item.

(15-17) Place of publication, production, or execution.
If the place of writing of the manuscript is explicitly stated, then fill this in using the MARC code list for countries, or if there was more than one place, use code “vp” ( for various places), or the code “xx^” (“no place, unknown or undetermined”). If you are making a 500 note on place of writing, be sure the coding here agrees.
