The Crystal Text by Clark Coolidge. Sun & Moon. 1986, 1995.

I never mark up my poetry books. Yet I make an exception with Coolidge. I always mark the poems, or sections of poems, that I like the best. Two check marks next to a passage means that I think it truly extraordinary. The Crystal Text is one of my favorite books of all time, and I am constantly marking new passages each time I read it. I can go through again and read only those passages marked twice. The book still has some passages I have a harder time getting through. Yet I wouldn't wish them absent from the book.
