"On the occasion of Eric Orr's exhibition at (Anders Tornberg Gallery, Lund, Sweden, 1990) Orr presented the book / object 'Zero Mass: The Art of Eric Orr,' a 330-page volume, bound in anodized blue steel. The book is comprised of extensive images and text, with some fifty full-color reproductions of the artist's work. This book-project was conceived by Eric Orr, his friends: artist James Lee Byars and critic Thomas McEvilley during a journey to Egypt in early 1989. The outcome is an exceptionally varied and generous work, consisting of a novella, explanatory texts, assorted notions, references, and some unexpected events. ‘Zero Mass’ serves as a quasi-catalogue raisonné of Eric Orr (1939 - 1998). ‘Zero Mass’ includes a unique multiple by James Lee Byars (1932 - 1997), a handmade ball of fired clay, titled by Byars "The Sphere of Generosity." Book and multiple are housed in a molded Styrofoam box, which is packaged within inside a screenprinted cardboard sleeve.

A number of additional highlights include "The Matter of O" [pp. 15], on which the Orr stamped a ring of his own blood - a la a coffee stain. The "Skull Page" (pp. 163-4) is noted within the colophon as being an inserted page of handmade paper by Yoshio Ikezaki, using kozo fibers impregnated with powdered mummy's skull. Pages 25-26 are torn by Orr
