To Replicate on 24.05.05 1. Create a MARC modification template such as: Add new 500 $a value: This is a note 2. Find a bibliographic record which already contains text in 500$a or add it if it does not. 3. Apply the MARC modification template from the bibliographic page. See that the note is not added. Repeat these steps but find a bibliographic record in which the 500$a does not have any text. See that a note is added.* Repeat these steps for the record in which the note was added. See that a second note is not added. I tried other tags, such as adding a 655$a and was only able to add it one time and not a second time. In theory, the record should be able to have multiple 655$a. I was able to add multiple 500$a notes and 655$a tags using the basic editor as normal. I tested this on 23.05 and I could apply the same MARC modification template multiple times and add the note every time. *I was not able to replicate this consistently. On one site I was able to add the note and on another site the note was not added. The MARC modification templates and bibliographic frameworks were identical.The Frameworks had the 500$a enabled to show in the staff interface and editor.
