The collection John Cage describes in this letter was published by Something Else Press in 1969 under the simple title Notations. The anthology was co-edited and designed with Alison Knowles and with the help of chance operations based on the I Ching. Taken together, An Anthology (1962–63) and Notations document one of the most vibrant periods in the modern history of experimentation with interdisciplinary performance scores and notations.
