Verified — Primary archival correspondence — supplied scan
Ben Burns’s May 11 letter requests a Middlebury speech. White supplies a New London Junior College address on June 10, requests review of revisions on June 16, and the publisher sends galleys on June 18; the secretary returns reviewed proofs on June 21. June 14 correspondence separately pursues a Myrdal speech. Corrected dates replace the earlier May 13, June 12, June 21 and July readings. These are production steps, not full publication or fee records.
