Documents in this collection that were prepared by officials of the United States as part of their official duties are in the public domain. Some of the archival materials in this collection may be subject to copyright or other intellectual property restrictions. Users of these materials are advised to determine the copyright status of any document from which they wish to publish.

The copyright law of the United States (Title 17, United States Code) governs the making of photocopies or other reproductions of copyrighted material. Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction.
One of these specified conditions is that the photocopy or reproduction is not to be "used for any purpose other than private study, scholarship, or research." If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excesses of "fair use," that user may be liable for copyright infringement. This institution reserves the right to refuse to accept a copying order if, in its judgment, fulfillment of the order would involve violation of copyright law. The copyright law extends its protection to unpublished works from the moment of creation in a tangible form.
