Not only does the Advanced Editor hide the 001 field, but it also silently overwrites it, if it existed before. The documentation for autoControlNumber ( https://koha-community.org/manual/24.11/en/html/catalogingpreferences.html#a... ) says: “This will not affect existing records that already have a value in 001. The existing value will be preserved.” -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
