To mark the anniversary of the Sept. 11 terrorist attacks, there are many sobering books to choose from. Here are some suggestions:
-- "A Place of Remembrance," the official book of the National September 11 memorial.
-- "Memory Remains," a phographic essay about 9-11 artifacts that were preserved after the attacks.
-- "One Nation," Life's photos of the attacks and the people who were involved.
-- "Unmeasured Strength," a memoir by Lauren Manning, who lost her husband in the World trade center collapse.
