This is a fantastic book, if only for its rarity. I get the feeling that some of the work presented here is not the best on tap from the authors, but such is anthology publishing. I'm using it to assist me in learning Arabic, and the clean (newsprint-style Arabic) typefaces make it well suited to the purpose.
One caveat: the book is quite small, containing only 15 poems from each author and very limited biographical sketches that don't contextualize the writers as well as I would expect. It is most definitely not intended to be used as a text, and more serious students of Arabic poetry will, for this reason, find it lacking.
Adonis, who the editor rather spuriously claims as the Arabic T.S. Eliot, is best represented here - especially by his poem "The New Noah". Not exactly the Lovesong of J. Alfred Prufrock, but wonderful nonetheless.
