It’s a worthy topic, and the collection of photographs brings it to life, making it real for students.  I just wish the writing was stronger.  It’s adequate.  All the facts are presented.  I just wished they had been strung together more coherently, to actually make a story of the events.  It’s like they were constructing the text to fit the formatting (it all fits very nicely into outlined text boxes, with titles over each paragraph), instead of designing the formatting to enhance the story.
