Copyright and literary rights for materials created by Richard Halliburton in this collection are held by the Trustees of Princeton University. When copyright is held by Princeton University, researchers will not need to obtain permission, complete any forms, or receive a letter to move forward with non-commercial use of materials from Firestone Library. The 78 letters and 5 telegrams by Halliburton to Lawrance Chambers, his editor at Bobbs-Merrill, require permission from Louis de Rochemont if they are to be used for movie or TV productions. Single copies may be made for research purposes. To cite or publish quotations that fall within Fair Use, as defined under U. S. Copyright Law, no permission is required. For instances beyond Fair Use, any copyright vested in the donor has passed to The Trustees of Princeton University and researchers do not need to obtain permission, complete any forms, or receive a letter to move forward with use of donor-created materials within the collection. For materials in the collection not created by the donor, or where the material is not an original, the copyright is likely not held by the University. In these instances, it is the responsibility of the researcher to determine whether any permissions related to copyright, privacy, publicity, or any other rights are necessary for their intended use of the Library's materials, and to obtain all required permissions from any existing rights holders, if they have not already done so. Princeton University Library's Special Collections does not charge any permission or use fees for the publication of images of materials from our collections. The department does request that its collections be properly cited and images credited. More detailed information can be found on the Copyright, Credit and Citations Guidelines page on our website.
