Contains books shelved by Derrida in his Studio, an addition to the house that served as Derrida's principal work environment from the time it was built in 2001 up to his death in 2004. Books are represented here as inventoried in 2011. Also includes books not inventoried in 2011 (hence presumably not shelved in the Studio at the time) but located in the Studio at the time of packing the Library for shipment to Princeton University Library.

Consists of manuscripts, both bound and unbound, mostly oversize, and artwork/ephemera housed in a variety of oversize containers.

Series 1 primarily pertains to the land and water rights of specific American Indian tribes or peoples. Most of the communities represented by Byler are native to the Southwest, especially Arizona, though issues related to tribes and peoples residing in Washington state, the Midwest, and the Southeast are also documented.

The Research Materials series contains materials collected by Hirschman as he conducted his research. The majority of the series is composed of photocopies and offprints of articles and reports, as well as some newspaper clippings, about Argentina, Brazil, Chile, Colombia, Mexico, and Latin America in general. These papers cover a range of economic, social, and political issues, providing views of the conditions in each country and the region. The series also includes articles about political theories, philosophies, and world economic and political history, and Hirschman's notes from his travels to Latin America.
