This was an inspired project, and yes, you should probably have it on your shelf. I do NOT recommend reading it cover-to-cover at speed, because this material is mostly quite depressing.
Forché has collected "poetry of witness" and grouped it by catastrophe. We have Armenian Genocide, World War I, Revolution and Repression in the Soviet Union, The Spanish Civil War, World War II, The Shoah, Repression in Eastern and Central Europe, War and Dictatorship in the Mediterranean, The Indo-Pakistani Wars, War in the Middle East, Repression and Revolution in Latin America, the Civil Rights Struggle, Wars in Korea and Vietnam, Repression in Africa/Apartheid, and Revolutions and the Struggle for Democracy in China. Dark and powerful subjects, producing many dark and powerful poems.
My one quibble with the selection is that this book would be more accurately titled "Poets of Witness" because some of the poets suffered in these periods, but many of the poems don't really reflect that.
The collection is too large for me to list all the standout poems, but the selection from Hilda Doolittle's "The Walls Do Not Fall" is worthy of study, as is George Seferis's "Last Stop." No one would be surprised at the exclams next to poems by Grass, Spender, Simic, Levi, Cavafy or Neruda.
This came out in 1993, and the authors' dates are listed, so I decided to update my table of contents. I was saddened, but not surprised, that in the thirty years since publication 36 of the authors had died. This fact reminds us that the anthology is very much a product of, and memorial to, the twentieth century. It's a worthy monument, and I do suggest finding a copy.
Mine is going on the shelf of exceptional works, where it can be consulted again.
