[Apologies for cross-posting, users and devel] Marc 952 $i, $k are not used in "standard" Koha. They can be added to the default framework (allowed by Koha), but this appears to require a modification to the Mysql structure. Has anyone tried to do this? Background: for Serials, we want to add at *item* level "Extended Keywords" (952$z is limited to 255 characters) and "Abstracts" (at *biblio* level, we use 520 $a and $b.) This will require new "Koha Fields" - e.g, in the same way that 952$z uses "items.itemnotes" we will need to introduce "items.itemkeywords" and "items.itemabstracts". I am looking for suggestions as to how to best add these fields so that they can be usefully searched by the OPAC - and of course for any pitfalls or showstoppers. Thanks Paul Tired old sys-admin
