Continuing with my book research, I came across two in-depth, historical accounts of Armenia and the Armenian Genocide, in National Geographic Magazine:
Armenia and the Armenians
National Geographic | October 1915
The Land of the Stalking Death: A Journey Through Starving Armenia on an American Relief Train
National Geographic | November 1919
In Sunday school (nearly 30 years ago), Dr. Zaven Daderian told our senior class about the wealth of documentation of the Armenian Genocide in the periodicals of the time, including the New York Times and National Geographic. He was right. See for yourself.
And, thank you Dr. Daderian, for educating us about our history.
