The History Department seeks to respect all copyrights and to acknowledge its intellectual debts. The texts scanned for the project are all in public domain. The electronic forms of the texts created by the HHTP are under copyright. Permission to copy and use the texts is granted for educational purposes. Permission is not granted for commercial uses.

Currently, most of the scanned texts have been checked only once for accuracy and thus may contain errors. Bibliographical information and acknowledgements for scanning, editing, and proofreading are found at the beginning of each text.
