Once NARA decides to release the requested records, in whole or in part, we will inform you in writing. Our response will tell you how much responsive material we found, where you may review the records, and the copying or other charges due. If the records you sought were released only in part, we will estimate, if possible, the amount of the withheld information. Also, if we deny any part of your request, our response will explain the reasons for the denial, which FOIA exemptions apply, and your right to appeal our decisions.
