Query: So hard to read, it hurts

Don't try using this book as a textbook. Don't try to study Damage Mechanics on your own with this book. Don't try to use it as a reference to learn quickly about some aspect that interests you. I guess is a treatise written for the few that already know this stuff. Written by a knowledgeable researcher, the book is *very* hard to read. Read instead his 1989 paper "Damage Mechanics" in Mechanics of Materials, p. 117-197. The subject index is inadequate; you cannot find anything relevant with it. I am hoping Amazon or Google will scan this book and make it searchable. The book emphasizes the micro structural aspects of damage mechanics. At 761 pages typeset in 8 point font (may be less) and containing *very* long passages, it is *very* hard to read.
