Hi all, I am looking here: Home > Administration > MARC frameworks > Default framework structure > Tag 952 subfield structure > Edit subfields constraints > Other options (choose one) What do the following plugins do? stocknumber.pl stocknumberAV.pl stocknumberam123.pl I know if you link stocknumberAV.pl with, say, 952$i, you can auto-generate an inventory number as you create item records. But I don't know why there are 3 stocknumber plugins. Many thanks, Craig Butosi, MA, MLIS, B Mus (Hons.)
