Dear All, I am trying to create new authority types in KOHA 21.11 on Ubuntu 20.04. I am following this documentation Create new authority type - Koha Wiki ( https://wiki.koha-community.org/wiki/Create_new_authority_type ) In the section on Zebra, * I cannot understand how the att numbers are defined * I cannot follow the next two steps, which require record.abs file. I cannot find the file. Neither the one in biblios nor in authorities folder. I need to create two authorities, namely, publisher and place of publication to accommodate my existing data which I will be migrating to KOHA. Support will be greatly appreciated With best regards, Naveen Ali ITM-JE (EAKL) Inst Representative for HEC Digital Library Resources. NEDUET, Karachi.
