Throughout history, humans have sought out substances to color, coat, and cover dwellings, objects, and bodies. Modern inorganic pigments and dyes joined natural and organic substances used by the ancients. The properties of one substance, lead white, once made it the pigment of choice in white paint. However, the toxicity of lead contributed to a public health crisis.
Textbooks and teachers often tell students about German scientist Alfred Wegener who went public in 1912 with his theory of continental drift. The scientific community did not widely accept Wegener's ideas during his lifetime and often derided colleagues who entertained the theory. Wegener passed away in 1930. Even as Marie Tharp was creating maps in the 1950s, scientists were actively constructing ideas and compiling evidence related to seafloor spreading and magnetic striping.
What might a map from 1977, a poster from 1944, and a newspaper article from 1915 have in common with three twentieth century wars and the theory of plate tectonics? These three digitized artifacts in the Library of Congress’s collection have quite a bit in common when it comes to the emergence of evidence supporting a key theory in Earth science.

The award, co-sponsored with the Consortium of Latin American Studies Programs, recognizes work that "authentically and engagingly portrays Latin Americans, Caribbeans, or Latinos in the United States." These diverse stories can be highlighted and brought to life through the use of primary sources.
I have never been to Syria. I had only read about and seen images of the ancient ruins in Palmyra. I knew the 2,000-year old Greco-Roman structures were falling apart and had been for centuries. I had, however, no personal experience with them. But late last month, when news reports detailed their destruction, I found myself very upset, and tried explaining why to my children.
