One of my most favourite books on writing is her book, "What is found there: Notebooks on poetry and politics" ... of which Nadine Gordimer had said:
"In her vision of warning and her celebration of life, Adrienne Rich is the Blake of American letters"
I must confess I did not like her final collection, Telephone Ringing in the Labyrinth: Poems 2004-2006, Norton (New York, NY 2007) But perhaps that is just my taste. It felt unfinished, as if I were reading unedited notebooks. Maybe that was her intention. I need to find that out.
