correcting proofs

I’ve spent a couple of hours correcting proofs of a paper.

There were several … interesting … changes made by the typesetter.

But the one the really had me yelling at the screen was in some mathematical text.  We had introduced an operator called redacted (well, it wasn’t actually called that, but I’m protecting the guilty here).  We consistently used a sans serif font, to distinguish it from other terms.

In some places it had been changed to redacted.  In some places it remained as redacted.  And in other places it had been changed to redacted.

Aaaargh!!!
