Hi, Adam-- If we do want an authority controlled added entry for publisher, we put it in a 710 field. Since the 260 (or 264) field is transcribed from the item, it has to match what is in the item, which may not match the authoritative form of the publisher's name. (We use MARC21, by the way.) Our authority records for publishers are normal corporate body authority records (i.e., 110s.) We have never traced publisher's locations, but, again, the information in the 260 (or 264) is transcribed from the item. I have heard of special collections that create an authority controlled added entry for place, and the ones I've seen are based on geographic authority records (151s) and traced in 751 fields. I have no personal experience with doing this in Koha, though! I hope this is helpful! Cheerio, h2 ~~~~~~~~~~~~~~ Heather Hernandez Technical Services Librarian San Francisco Maritime National Historical Park Research Center 2 Marina Blvd., Bldg.
