45 C.F.R. § 2507.6
(b) Directions for making requests. All FOIA requests must be submitted in writing to the FOIA Officer at AmeriCorps headquarters in one of the following ways:
(c) Description of records sought. Requesters must provide enough detail about the Agency's records they seek that AmeriCorps personnel can find responsive records, if they exist, with a reasonable amount of effort. To the extent possible, requesters should include information that helps identify the records, such as dates, titles or names, authors, recipients, subject matter of the records, or assigned reference numbers. Requesters may adjust their request or ask for advice on writing a request by sending a note to foia@cns.gov.
