Open World (note: this is listed as "Open Worlds" on [...]; the correct title is "Open World") "Le Nouvel Obsrvateur", Paris, says that Kenneth White "is bound to appear as the foremost English-languge poet of these times" (from the cover), and I agree. I first ran across his name and some of his poetry in books by J. Philip Newell, then found "Open World" on amazon.com and bought it. It comprises his collected works from 1960 to 2000. Each time I pick it up and open it, I find new things that I had missed in a previous reading, like finding gold where you had looked before and there, on a second or third or fourth digging, there it is, right before your eye.
Born in Glasgow in 1936 and raised in western Scotland, Kenneth White is also an essayist, travel writer and held the chair of 20th Century Poetics at the Sorbonne from 1983-1996.
If you haven't heard of him, buy this book and read it; it's become one of the most important books in my library.
