Visiting the Archive

Content section: 

The Mark Twain Papers reading room and Project offices are located in The Bancroft Library, room 475. Enter Bancroft from the second floor of Doe Library or from the east entrance to Doe Annex, facing the Sather Campanile and the Esplanade.

Before Your Visit

Please schedule your visit in advance so that approved materials will be ready when you arrive. Our hours are shown on Bancroft’s home page. For more information about visiting the campus, see Visit Berkeley.

Mark Twain Project online contains our public-facing correspondence catalog with records for letters held all over the world, not only at MTP (“CU-MARK”). OskiCat has records for all UC Berkeley libraries; for MTP’s holdings, choose “Mark Twain Papers” as the search location instead of “Entire Collection”. Our Writings and Images catalogs remain private, for now, but inquiries are welcome.

Please plan to leave your belongings in a locker near Doe Annex’s east door and to register as a visitor at the Bancroft security desk. Registration requires picture identification.           

All Bancroft Library collections are non-circulating. Please read Bancroft’s Reading Room Rules, and Rights & Permissions pages before your visit, as well as MTP’s Permissions & Duplication page.
