Publication Info Fields Index and Display

Each record should include one or more fields relating to its publication, manufacture, distribution, copyright, and which edition this record refers to. Much of the time, it's contextual information to help users verify that the item they're looking at in search results or in item pages is the one the want. For example, it's important to know that the copy of Night of the Hunter which you're looking at is the special edition, or that a textbook is the 11th edition from 2008.

Although this info can be recorded in a number of places and mean a number of things, we're going to start with fairly basic publication info for search result display, add other imprint information in the single item display, index the copyright date if there is one, and index the edition for both search result/single item display.

Publication and Edition Fields

MARC field	indicators	description
250	n/a	edition statement
255	n/a	cartographic mathematical data
260	n/a	original publication statement. later broken out by 264 to handle multiple types of info using indicators
264	*0	information about how the work was produced
264	*1	publication statement
264	*2	information about how the work was distributed
264	*3	Information about how the work was manufactured
264	*4	Just the copyright date in subfield c. Of note, this may be in [ ] with c or with a copyright symbol or other prefix, not solely a 4-digit year date
775	0*	other edition entry, contains data about other editions of a work by the same publisher

No record should have both a 260 and a 264.

Publication fields for Search

People may search by publisher name or manufacturer/printer name, e.g. "I want to find all the library juice press books we have." Publishers and manufacturers should be indexed for keyword search. We may also put it in advanced search later.

• Publisher/Manufacturer - 260b:264|*1|b:260f:264|*3|b (trim punctuation)

Publication and Edition Fields for Display

If there is a 264, there may be more than 1 of them. For the search results, we'll display just whichever statements apply to the publication action. For the overall record, we index and display whichever fields exist. We also display the copyright.

• Display fields/labels search results view:
  • [No Label, search results view] - publication_display_ssm - 260abcefg3:264|*1|abc3
• Display fields/labels item view:
  • Published - overall_imprint_display_ssm - 260abcefg3:264|*0|abc3:264|*1|abc3:264|*2|abc3:264|*3|abc3
  • Edition - edition_display_ssm - 250ab3
  • Copyright Date - copyright_display_ssm - 264|*4|c
  • Cartographic Mathematical Data - cartographic_math_display_ssm - 255abcdefg
  • Other Edition - other_edition_display_ssm - 775|0*|iabcdefghkmnors

Publication Year Facet

4 digit publication year facet uses a similar logic to Traject's marc_publication_date:

• prefers using 008, but will first resort to 264|*1|c and then to 260|c if no date found.
• If 008 represents a date range, takes the midpoint of the range, only if range is smaller than estimate_tolerance, default 15 years.
• Ignores dates below min_year (default 500) or above max_year (this year plus 6 years).

Publication Info for Illiad and Aeon

• publication date (and/or range): 260c:264|*1|c
• publisher name: 260b:264|*1|b
• publication place: 260a:264|*1|a

Other Thoughts

The following MARC fields are split out with nuanced name/description. For now, we're going to do a simpler index/display, but we should keep these on hand as an alternative.

# 264|*0|abc3 - production
# 264|*1|abc3:260abcefg3 - publication
# 264|*2|abc3 - distribution
# 264|*3|abc3 - manufacture
# 264|*4|c - copyright date
# 250ab3 - edition statement (trim punctuation)
