The NYPL now has a flickr account and has started the process of putting up bits of it’s photo collection. I’m sure this is going to be an amazing resource soon, and you can still find their fantastic library of photos online at their own site. Photo of a German Stowaway at Ellis Island.
I’d been looking through NYPL’s Digital Gallery for class (I’m doing a magazine spread on Art Nouveau) when I found this collection of Lewis Wickes Hine’s photos. He documented child labor, Ellis Island Immigrants, working and domestic conditions in America between 1905-1938. These photos are beautiful because they are a dark part of our history.
