The Nation, 'The Novelist and the Murderers', covers the effect of the book's publication on Guatemala and WNYC follows up with an interview on the same topic:
Global Voices Online records the thoughts of Guatemalans ten years after the murder: Remembering Bishop Gerardi and His Report “Never Again!” Finally, for current human rights concerns and actions: AIUSA's Guatemala page.
