Sam,
I agree. Our procedure states that QA, me, assures that revised documents are to be returned to QA for disposal or archives. We also will include a acknowledgement sheet that states procedures, affected sheets, etc..that are to be replaced. I have actually had the wrong pages removed and replaced. This check allows you to see that this has not happened. I was just confused regarding "evidence" that obsolete documents were, in fact, destroyed or archived. Archived was easy. Thanks for the reply.
