Here's an excerpt from the press release:
Robert Darnton, a DPLA Steering Committee member and University Librarian at Harvard, said, "The association between the DPLA and Europeana means that users everywhere will eventually have access to the combined riches of the two systems at a single click. The aggregated databases will include many millions of books, pamphlets, newspapers, manuscripts, images, recordings, videos, and other materials in many formats."
Jill Cousins, Executive Director of Europeana, welcomed the agreement, saying that "Europeana was designed to be open and interoperable, and to be able to collaborate with the DPLA is a validation of that aim. By this combined effort on two continents, Europeana and the DPLA hope to promote the creation of a global network with partners from around the world."
Another outcome of this collaboration will be a virtual exhibition about the migration of Europeans to America. The DPLA and Europeana will demonstrate the potential of their combined collections by digitizing and making freely available material about the journey from the Old World to the New. This pilot project will include text and images about the experience of the uprooted as they abandoned their homes to seek a new life thousands of miles across a treacherous ocean. Letters, photographs, and official records open up unfamiliar views into the harsh world inhabited by Europeans from the shtetl communities of Russia to the peasant villages of Ireland. And equally vivid testimonies illustrate the culture shock and hard lot of the immigrants after their arrival. Everyone in the United States, including Amerindians, descends from immigrants, and nearly everyone in Europe has some connection with migration, either within Europe itself or across the ocean. All will be invited to stroll digitally through this rich exhibition.
