Just a quick update with a new workflow to add to this informal guide to my use of MarcEdit. The way our consortium (CARLI) displays format facets in VuFind recently changed and some of the MARC records for ebooks needed to be updated. One thing that needed to change was the “Bibliographic Level” in the leader needed to be changed from “d” to “a.”
I was unsure how to do this, but a simple google search resulted in Terry Reese’s helpful blog that explained the process and the function. I snapped a quick screenshot for future reference.
Unlike other subfields, the Leader is character specific and things cannot simply be deleted; they much be carefully replaced to preserve the order and spacing. The “Bibliographic Level” is recorded in the 7th position, so I ran this global change command and quickly made the switch to all 3,500 records.
