I can relieve your mind somewhat. I have seen many, many
modifications to 4xx field indicators... including two on an authority
control vendor supplied printout for n86136259 and n86136261.
However, I hope someone with much more knowledge of of the
specifics of the project will share that information with all of us.
I only learned of this project when my usual monthly update list
grew from around 2,000 records to over 9,000 records. At that point
I started asking questions.
