The discovery of the audio file sheds new light on another publicly owned document—the typewritten speech delivered by Dr. King that evening, now in the collection of the New York State Archives. It is now evident that the editing marks made on the speech were made by Enoch Squires, the audio engineer who made the recording. Presumably, he marked the document after listening to the recorded speech. The handwriting on the speech is identical to Squires’ labels and notes made on his audio tape collection, donated to the State Museum.
