Remembering Our Ancestors: Maps and Genealogy Resources for Armenian-Americans

As an Armenian-American keenly aware of the devotion to lost homeland of my ethnic compatriots, I’ve always been on the lookout for Armenians among the researchers from many large ethnic groups who have found their way to the Map Division. April 24 is the 100th anniversary of the beginning of the Armenian Genocide, and one way to honor those who were not able to find refuge is to learn all we can about them and celebrate our link to them.Read More ›

Peeling Off The Painted Layers of NYC Walls: Experiments With The Google Street View Archive

As a web developer who works on a screen and an illustrator that works on paper, I have always admired those who could paint big—often on impossibly large and inconveniently placed walls—only to be erased in a matter of weeks or days. The ephemeral nature of street art is what makes it simultaneously appealing and frustrating as a viewer. However, Google Maps recently rolled out a feature allowing users to go back in

Classroom Connections: 'Grace Aguilar's American Journey,' A Common Core-aligned Research Experience (Gr. 11-12)

By 1900, New York City and the United States were undergoing waves of dramatic, traumatic change. Industrialization, Reconstruction and a surge of immigrants from across the globe were remaking every aspect of life, from transportation to education, leisure, labor, race relations and the status of women.

But what would it look like if we founded The New York Public Library today?

Look around you and you’ll notice that
