Why am I being charged a correction fee to make dissertation/thesis revisions?

When we process a dissertation/thesis through our editorial workflow, we create multiple copies of microfilm that are stored in separate climate and humidity-controlled vaults around the United States.

We also store multiple digital copies of the PDF in secure cloud storage and other storage arrays.

Due to the extensive manual work required to recreate new copies and replace them in our many storage environments, we charge a $47 Vault Repair/correction fee.
