"Archivist of the United States (he's also a librarian!) and host of the DPLA Plenary (at took place at "his house"), David Ferriero, has blogged a brief item about the event on his AOTUS blog.
On Friday more than 300 government leaders, librarians, technologist, makers, students, and others interested members of the public “occupied” the National Archives to share their visions for the DPLA. The Sloan and Arcadia Foundations announced $5m in additional funding for the Project. Europeana, the European Digital Library, announced its intention of collaborating on interoperability among libraries, museum, and archives in the United States and Europe. And David Weinberger announced that his “head and heart are exploding to interoperate!”
A series of nine Beta Sprint demonstration presented possible DPLA prototypes. I am especially proud of the one done collaboratively by the National Archives, the Smithsonian Institution, and the Library of Congress. Wouldn’t it be wonderful to seamlessly search across all three collections?!"
