Econometric Society
The HOPE Center worked with the Econometric Society to create a digital archive of documents and other materials related to the founding and development of the Econometric Society. Two of those digitized documents—the announcement of the organizational meeting in 1930 and a memo detailing the creation of the journal and the election of the first fellows—can be accessed on the society's website.
For more on the project, please see this story that describes the initiation of the project and the exploratory work done by two graduate students at Duke, Matt Pahnans and John Singleton. A slide show available via dropbox accompanies the story.
