The Papers of James Madison went digital in April 2010 with the online alpha prerelease of the seventeen Congressional Series volumes through ROTUNDA, the digital publishing wing of the University of Virginia Press. These volumes, part of the American History Collection, are available on a subscription basis.

In addition, preliminary transcriptions of more than 5,500 as-yet-unpublished Madison documents are available for free through the ROTUNDA Founders Early Access project. These documents were prepared and reviewed by the staff of Documents Compass, a program of Virginia Humanities, but have not yet been reviewed or annotated by Papers of James Madison staff.
