Another collection of Dr. Cornett’s correspondence, this one arranged alphabetically by the correspondent’s surname. Unlike series 5, this series mixes incoming and outgoing correspondence, but most is still related to Cued Speech.

Some correspondents receive individual files, particularly Mary Haney of the New York School for the Deaf, an early adopter and strong proponent of Cued Speech. Also includes a file requests received from parents and educators for copies of Cued Speech handbooks.
