On June 24-26 I attended the 2009 NDIIPP Partners Meeting in Washington DC. Although it has grown from the early years, I believe this year's attendance of 150 people is similar to last year's.
Clay Shirky, author of "Here Comes Everybody", gave the keynote on Wednesday morning. Hopefully the Library of Congress will post a video of the keynote soon. If not, take a look at some of his other presentations -- you will find them enjoyable and informative.
On Thursday morning I presented a summary of Martin's PhD research, the tangible product of which will be a FireFox extension called "Synchronicity":
The presentation was very well received and there is a lot of interest in the extension. There were several interesting break out sessions, but the real news was on Friday when Martha Anderson (LC) introduced the upcoming National Digital Stewardship Alliance (NDSA). Details will be forthcoming, but it appears to be envisioned as a cooperating set of digital archives.
