How to redact the publisher-list

I want to remove publishers from the pull down menu in the publisher-field. Is it possible somehow?

Hi,

I am not sure what you exactly refer to. Could you please add a screenshot showing what field you mean?

I donot see a pull down menu in the publisher field. Make a screenshot, as Christoph suggested.

I mean the drop-down-list, that opens, when I start to write into the publisher-field for a new entry.
