Artist's book by James Hoff based upon artists' book "Secrets : Variable Piece 4," by Douglas Huebler. To conceive the book Hoff dusted a copy of the original Huebler book revealing fingerprints of the book's prior readers. "Secrets" was index of secrets collected by Huebler during the exhibition Software, held at the Jewish Museum, New York, September 16 - November 8, 1970. "Nearly 1,800 'secrets' were submitted for exchange and have been transcribed exactly as written except that surnames have been edited: all are printed in this book and join with this statement as final form of this piece." -- from book's back cover. Date of publication often stated as being 1973, however, that date references when work was conceived, not date of book's publication, which was in 1977. [Publisher, Printed Matter, was not founded until 1976.]
