This book is a well illustrated biography of Indiana (born Robert Clark) by Susan Ryan that was an outgrowth of a PhD thesis. It deals mainly with Indiana's work from the late 1950's to the early 1970's with emphasis on his visual language works and worded sculptured columns called "herms." The art works are critiqued by Ryan. There are sections that deal with Indiana's poetry and his artist statements. It mentions that Indiana was influenced by the poems of Jose Garcia Villa. -- Source of annotation: Marvin or Ruth Sackner.

Kostelanetz writes that "this book differs from most other writing about Cage in emphasizing his professional adventurousness, acknowledging not only his music but his theater, writing, radio, visual art, political philosophy, and much else, all reflecting a career based upon artistic (and thus artists') freedom...In its variety and its departures from expository conventions thirty Years is probably a more Cagean book than a measured continuous exposition." The design of this book utilizes page numbering through overlaying each page of text with a large gray number. -- Source of annotation: Marvin or Ruth Sackner.
