I have never had to defend myself or my staff against claims of falsifying a quote in a yearbook, but I am ready if it happens. This quote collection form is one of the ways we proactively protect ourselves. My staff members collect a signature for each and every quote that is used in the 400+ pages of our yearbook.
This form is a requirement for all staff members, and I use it as a contributing factor in their grades. Additionally, I keep all forms on file, just in case.
You never know!
