Mark Twain Papers

The Mark Twain Papers, a research center at The Bancroft Library, holds a preeminent collection of manuscripts, letters, photographs, marginalia and other documents created by and related to 19th-century American author Samuel Clemens, aka “Mark Twain.”  The Mark Twain Project, undertaken by the Mark Twain Papers staff, is a comprehensive scholarly edition designed to include everything of significance that Mark Twain wrote.


Oral Histories

The Oral History Center, formerly called the Regional Oral History Office (ROHO), has produced over 4000 oral histories.  These carefully researched, audio/video-recorded and transcribed interviews span a wide array of subjects. These include politics and government; law and jurisprudence; arts and letters; business and labor; social and community history; University of California history; natural resources and the environment; and science, medicine, and technology.

ROHO began in 1954, but the tradition of preserving oral histories at this library harkens to Hubert Howe Bancroft’s practice of gathering “dictations” from pioneers in the 19th century.



The Bancroft Library houses the Center for Tebtunis Papyri.   This collection of over 26,000 Graeco-Roman era papyri and related artifacts were excavated from the town of Tebtunis in 1899/1900.  CTP and local and regional partners have created a database to track Bancroft’s papyri collection as well as those of neighboring institutions.
