Hi! It makes me SO happy to see this!! This is the relevant documentation for the MARC21
...the MARC21 76X-78X Linking Entry Fields: https://www.loc.gov/marc/bibliographic/bd760787.html (I was so excited I mistyped and my previous comment got saved before I finished!) ByWater has created custom XSLT so that the field linking of these fields works via enabling linking on the control numbers in the $w of these fields: https://keys.bywatersolutions.com/ They are willing to share this XSLT so this linking can get into the community version, if that would help. In our catalog, selecting the hyperlinked control number in the $w of the 76X-78X Linking Entry Field executes a search on the 001 of the target record. It is not a simple search, since we, like many, many libraries, use OCLC, so our 001 fields contain OCLC numbers with prefixes--but it works! So happy to see this omnibus!!! --h2
Hi Heather, I had planned to add you when I have a more complete picture of open bugs concerning 7xx fields :) I think any specifics for OCLC + $w should go on a separate bug linked to this one. We might want to tie it to a new preference or similar. As I have never used OCLC, I am not aware of what needs to be done exactly, but we need to be careful not to break things for other use cases (I think union catalogs in Finland, Sweden and Germany at least are using $w these days :) )
Hi, Katrin! Specifics of linking (e.g., $w vs. $a/$t, and/or with different types of $w numbers) in a separate bug, perhaps (hopefully!) tied to a syspref makes so much sense. Thank you!!! h2
Hi! I created a ticket with ByWater, requesting that they post the code from our catalog (keys.bywatersolutions.com) that makes our 7XX linking entry fields work. --h2
Hi Katrin, The code that Heather has requested is available here! https://github.com/bywatersolutions/bywater-koha-xslt/commits/keys Please let me know if I can help out further.
