Hi Thomas, when you have a 8xx for a traced series, you usually have a 490 with first indicator = 1 as well. See: https://www.loc.gov/marc/bibliographic/bd490.html https://www.loc.gov/marc/bibliographic/bd830.html The 490 is also present in your sample record from DNB. Hope this helps, Katrin
Not sure what you mean by "490 ind". But the relationship is definitly not 1:1, but n:1 (i.e. we're linking from a child to a parent)
In this case linking horizontally to the other parts of the series instead of linking to the set record was chosen by design, assuming it would make more sense to the user. Especially since untraced series don't have a set record and the link can only link to the parts. I think we are using this 830$w to link not horizontally, but vertically, from a book up to a sort of series ("Reihe"). We're not 100% sure this is correct, so we copied what DNB is doing (see again these links):
https://portal.dnb.de/opac/simpleSearch?query=9783847703389 linking via 830$w to https://portal.dnb.de/opac/opacPresentation?cqlMode=true&reset=true&referrerPosition=0&referrerResultId=%229783847703389%22%26any&query=idn%3D015935620
But it could be changed locally of course as you said by just changing the index. If you don't want to change the XSLT file this can also be done quite easily with jQuery in OpacUserJs: ok, that's another way to correct the param name.
We were just not sure if using 'rcn' instead of 'control-number' was a bug in Koha or our MARC. It seems it is neither, so we'll use a workaround to "correct" the param name.
Greetings, domm
