Among the correspondents are many noted economists, including Yoram Barzel, Robert Bates, Reuven Brenner, Robert Clower, R. H. Coase, Robert Fogel, Robert Haveman, Robert Keohane, Simon Kuznets, Deirdre N. McCloskey, Elinor Ostrom, Vernon Smith, T. N. Srinivasan, John J. Wallis, and Barry R. Weingast.

The papers of university professor and Nobel Prize-winning economist Douglass C. North span the dates 1942-2012, with most of the papers being dated between 1970 and 2012. They consist chiefly of professional correspondence written and received by North, writings by North and other colleagues, and files on conferences attended by North. There are also materials relating to courses he taught. The collection documents North's career as an economist and professor at Berkeley, University of Washington, Rice University, and Washington University (Missouri), and reflects his interests in economics, the economic history of the western world, transaction costs, economic development, institutional change, and industrialization and technology. More specifically, the papers document his long-standing interest in explaining institutional change and political economies without relying exclusively on neo-classical economic theories. His political economy draw him closer to approaches of classical political economy.

Among the correspondents are many noted economists, including Yoram Barzel, Robert Bates, Reuven Brenner, Robert Clower, R.H. Coase, Robert Fogel, Robert Haveman, Robert Keohane, Simon Kuznets, Deirdre N. McCloskey, Emily Chamlee-Wright, Elinor Ostrom, Vernon Smith, T.N. Srinivasan, John J. Wallis and Barry R. Weingast. Some of these correspondents are also represented in the Writings Series of this collection, a large group which contains drafts, notes, and reprints of writings by North as well as writings by his colleagues.

North's secretary Fannie Batt is an important factor for a proper understanding of the nature of this collection. After receiving the Nobel Prize in 1993, North's correspondence expanded substantially. Fannie Batt, his secretary at the Washington University in St. Louis, was tasked to take care of the correspondence for North. Her role impacted the subsequent arrangement of the collection. Materials are often Fannie Batt's printouts of correspondence for North. Most of the correspondence since the 1990s is carried through Fannie Batt's email address. Also, North's own responses to emails are not as frequent in the collection as one would expect. Existing responses were often dictated by North and typed by Fannie Batt.

Other large amounts of correspondence and other materials relate to Davidson's editorial work with many major economics journals, including the Journal of Post Keynesian Economics, which he founded; these folders typically contain correspondence between Davidson, journal referees, and authors.
