The Mark Twain Papers & Project is located at 2195 Hearst Avenue #330, Berkeley, CA 94720-6400, where it will remain throughout the building renovation of The Bancroft Library scheduled for 2005-2007. Open hours are Monday-Friday 9:30-4. It is best to contact staff in advance of a visit. Closed on national and university holidays.

The Mark Twain Project will be closed from June 1, 2008, to mid-Fall 2008 to move back to the newly retrofitted Doe Annex. Please plan your research accordingly.

Everything Mark Twain wrote for which the Mark Twain Project had even a partial text, as of the end of 2001, has now been published—either by Mark Twain himself, by various hands between 1910 and 1962, or by the University of California Press or The Bancroft Library between 1962 and the end of 2002, either in printed volumes or in one of three Microfilm Editions issued by The Bancroft Library in December 2001. Some works have also been published or reprinted in this period by other publishers under license from the University of California Press.

What Mark Twain himself published, or anything of his that others published posthumously before the year 1923, is in the public domain and may be quoted or reproduced in its entirety without permission. Mark Twain writings of any kind, whether literary manuscripts, notebooks, marginalia, or letters which came to light after 2001 and which were not published in the Microfilm Editions or elsewhere before the end of 2002 are likewise in the public domain.

Under “fair use,” quotation from any published work still under copyright is permitted without obtaining the copyright holder’s permission. But re-publication or reprinting of any whole work (letter, notebook, essay, etc.) so protected requires the permission of the copyright holder. Generally speaking, if publication occurred in 1962 or later, permission is to be obtained from the University of California Press. If publication occurred between 1923 and 1961, permission is to be obtained from the Mark Twain Foundation.

It is the responsibility of the requester (a) to determine the specific source of the words to be quoted; and (b) to quote them with reasonable accuracy and precision. Mark Twain Project staff can offer limited assistance to confirm original publication dates of certain works and, for material published in the microfilm edition, we will provide specific microfilm reel numbers for citation purposes. For further copyright questions and assistance you may wish to consult an attorney.
