Thank you so much for posting. I am particularly honored, as you were one of my sources.
My primary source was the book, Liberty’s Torch: The Great Adventure to Build the Statue of Liberty, by Elizabeth Mitchell, Atlantic Monthly Press, 2014.

The information on Schuyler was partly from your article as well as the National Park Service.
according to your recent article in the Smithsonian (sourced on the click-through link at the bottom of my article), you note that the National Park Service addressed how Schuyler came across “The New Colossus” in 1901.
Other sources included
“Emma Lazarus” by Kerri Lee Alexander, National Women’s History Museum. 2020. http://www.womenshistory.org/education-resources/biographies/emma-lazarus

In looking quickly through my notes, I am not finding Schuyler directly connected to the 1883 auction. We do know that she helped raise funds for adding the plaque to the pedestal. We’re traveling now. When I get home, I will likely make that change.
