The Goldwin Smith Collection is held at the Division of Rare and Manuscript Collections of the Carl A. Kroch Library, Cornell University. It currently consists of fifty-three boxes of material that includes originals and copies of correspondence, manuscripts, and assorted memorabilia. The original Goldwin Smith Papers were left to Arnold Haultain, his secretary and literary executor, who initially organized them and deposited them at the Cornell library. Since that time, original materials or copies have been added from archives all over the English-speaking world. Much of this collection has been microfilmed.
Also of value are the microfilms of correspondence between Smith and Lord Grey kept at the Kroch Library (the originals are held at the Department of Paleography, University of Durham, England).
The Ezra Cornell Papers, the Waterman Thomas Hewett Papers, and the Albert Henry Sewell Papers also at the Kroch Library contain some material relevant to Smith.
From the perspective of Goldwin Smith’s students, there is also the manuscript journal of Jared Treman Newman in the possession of Prof. Isaac Kramnick of Cornell University.
