The External Views on Princeton series documents the opinions and views of non-Princetonians about Princeton University. Princeton has—almost since its founding—been a favorite subject of writers, artists, and filmmakers. Though it is often portrayed with admiration, it is also sometimes the subject of criticism or parody. This series also includes rankings of universities that include Princeton, things named for Princeton, and lists of Princetonians awarded non-Princeton prizes and awards. A large section of this series consists of newspaper and magazine articles about Princeton (the bulk of which date to the nineteenth and early twentieth centuries). Because of the number of these that are oversize, an oversize run is included as part of the series. For media produced at Princeton or by Princetonians on subjects other than Princeton, see Series 24 (Multimedia). For other newspaper and magazine articles about specific time periods in Princeton's history, see the chronological section of Series 1 (General).

Consists of personal and family correspondence as well as business and legal correspondence.

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.
