Thanks for the tips. Will contact his son to find out if there are some "archives" available and report back if I get an answer.

Opening this topic to identify articles, lectures or liner notes by Gunther Schuller. Here are some I have found on the web: - article on Thelonious Monk in the Jazz Review here https://jazzstudiesonline.org/resource/jazz-review-vol1-no1-nov-1958 - "Sonny Rollins and the Challenge of Thematic Improvisation" here https://jazzstudiesonline.org/resource/sonny-rollins-and-challenge-thematic-improvisation - 3 part Tanner Lecture (Jazz a Historical Perspective / Duke Ellington / Charles Mingus) here https://tannerlectures.utah.edu/_documents/a-to-z/s/schuller97.pdf - article on Sarah Vaughan here https://jazzprofiles.blogspot.com/2020/02/sarah-vaughan-divine-one-by-gunther.html Are there other material available online, or that can be shared ? Thanks
